The following is a fusion of the current Photographer and Watcher advanced classes. They're both filled with arguably useless Features and other clutter, and also essentially fill the same niche. Hopefully something like this can pave the way for another more interesting advanced class for Researcher.
Watcher
Advanced Class
Prerequisites: Researcher, 16 WIS, Art Tool (Pricing Varies)
Cross-Class Prerequisites: 20 WIS, Art Tool (Pricing Varies)
Key Ability: Wisdom
Bonuses: +1 WIS
Class Features:
Close Watch, Natural Artist
Close Watch: S L
Static
Effect: X is your Wisdom modifier halved. You may move at a speed of X meters per round and remain undetected by any Wild Pokemon that cannot directly see you. Subtract X from 10, to a minimum of 5. This is how many meters you may be away from a Pokemon while you are in motion and remain undetected. If you are completely motionless, a Pokemon will only be able to detect you if they directly see you. A Pokemon with the Tracker Capability will detect you if they come within 5 meters of your location, even if you are motionless.
Natural Artist: S L
Static
Effect: Choose any form of art that allows you to copy a scene, such as sketching, photography, or painting. You are a master of this art form, and may perform it with incredible ease and unbelievable speed. Quick scene capturing takes less than a minute at most, and detailed pieces take no more than a day. Your art products are of high quality and may be worth decent sums of money, as decided by the GM.
The Pokemon Watcher is a Researcher very in tune with a Pokemon’s natural habitat. They can identify facts about a wild Pokemon’s living conditions such as the amount of Pokemon they live with, which nearby spot yields those family members and how easily they can tackle the foe at hand, just by looking at the wild Pokemon. Another talent a watcher has, unseen in any other trainer type, is that ability to locate and track down shiny Pokemon who make great pageant competitors or grand auction items.
Class Features
Applied Psychology: S L
Prerequisites: Watcher.
Static
Effect: People cannot lie to you. If information a person gives you is false, but they believe it to be true, you cannot discern this.
Battle Study: S L
Prerequisites: Watcher, has used Picture the Action successfully five times.
Static
Effect: There is no longer a limit to the number of Moves you may penalize through Picture the Action.
Berrydex: S L
Prerequisites: Watcher.
Static
Effect: You can identify any Berry, its properties and what it yields in terms of Contest Stats. When you are making Berries into Poffins, Shakes or PokeBlocks, you get +2 to your rolls.
Continued Observation: FA IL
Prerequisites: Watcher, 19 WIS.
Daily - Every 10 levels gained, you may perform this Feature another time per day.
Trigger: A Pokemon successfully flees from the Watcher or other allies.
Effect: You will be able to track the fleeing Pokemon for up to a mile from where it originally fled from. If combat is re-engaged after tracking down the Pokemon, it is considered a new encounter. You may also expend a use of Continued Observation to make a willing allied Pokemon re-roll a Tracker check. They must keep the re-roll.
Familiar Lands: S L
Prerequisites: Watcher, 19 WIS.
Static
Effect: While in any type of terrain that you are familiar with, you will immediately spot any anomalies in the general area. If non-native Pokemon or circumstances are in the area, you will know of their existence, but not immediately know where they are. Roll 1d20 and add your Wisdom modifier. If the total is 17 or greater, you can successfully find the anomaly. You may only attempt this check once per hour.
Improvised Camouflage: TA IL
Prerequisites: Watcher, has evaded hostile Pokemon with Close Watch.
Daily - Every 10 levels gained, you may perform this Feature another time per day.
Target: Trainers.
Effect: You spend ten minutes to fabricate a full-body camouflage suit that covers the target. The target gains a +2 bonus to all stealth-related checks and treats their Wisdom stat as being two points higher, but only when consulting Close Watch. When creating the suit, choose the environment that it is designed for. The bonuses the camouflage gives only applies while in the chosen environment. The wearer is also considered to be the type most fitting for the camouflage; you may not gain the Ghost or Steel types through Improvised Camouflage. If the wearer is hit with a super-effective attack, the camouflage is destroyed.
Pester Ball: TA IL
Prerequisites: Watcher.
Daily – Every 6 levels gained, you may perform this Feature another time per day.
Target: A wild Pokemon.
Effect: Pay 50. Roll 1d20 and add your Wisdom modifier. If the total is 15 or greater, Pester Ball is used successfully. The target must take its next turn to either immediately attack the nearest target it can reach, or completely avoid attacking you and your Pokemon, whichever you choose. The effects of Pester Ball last for one turn only. If you target the same Pokemon again, the total required to use Pester Ball is raised by 5 for each time it was used on the target before.
Picture the Action: TA IL
Prerequisites: Watcher, Natural Artist, 22 WIS.
Daily
Trigger: You or your Pokemon are attacked by a Move.
Effect: The Move will not miss its Legal Targets upon activating Picture the Action. Roll 1d20 and add your WIS modifier. If the total is 20 or greater, you successfully create a picture of the Move. While this picture is in your possession, that Move will require +2 to hit you or your Pokemon during Accuracy Check. You may only apply this penalty to one Move per encounter. You may not copy this picture in any form; it is a unique piece.
Picture Tutor: TA IL
Prerequisites: Watcher, has used Picture the Action successfully ten times, 25 WIS.
Daily
Target: A Pokemon.
Effect: Select a picture taken with Picture the Action, that is of a Move that can be learned by the target normally through any source. Roll 1d20 and add your WIS modifier. If the total is 21 or greater, the target learns that Move. Regardless of success, the picture is destroyed. If Picture Tutor was used successfully, you may never use it on the target again
Pokemon Finder: TA IL
Prerequisites: Watcher, 20 WIS.
Daily - Every 10 levels gained, you may perform this Feature another time per day.
Target: Wild Pokemon.
Effect: Roll 1d20 and add your Intelligence and Wisdom modifiers. If the total is 18 or greater, choose one of the following traits: Species, Type, Nature. You can start an encounter with multiple Pokemon whose chosen traits are the same as the targeted Pokemon's. If Pokemon Finder was used during an encounter, you must wait for the current encounter to end before starting a new one.
Pokemon Seeker: TA IL
Prerequisites: Watcher, Pokemon Finder.

Shiny Hunter: TA IL
Prerequisites: Watcher, 24 WIS.
Daily
Target: Anywhere on a route.
Effect: Roll 1d100. If you rolled equal to or under your Wisdom modifier doubled, a Pokemon with rare and unnatural qualities will appear in the next wild encounter. These unusual qualities may range from unique typing, unusual coloring, or almost anything else.
