For a home game, I'm looking at adapting the Wave Warden Ranger archetype to Hunters.
Most of it looks like it should drop right in to place. Both classes have Track, Woodland Stride, and Swift Tracker, so that's pretty easy. I'm not so sure what to do with the modifications to Favored Terrain and Combat Style Feats, though.
My initial thought is to drop in one of them in place of Animal Focus. Animal Focus tends to be passive bonuses, so maybe the Favored Terrain stuff fits well there? I'm not sure if Favored Terrain ends up being weaker overall, though.
Then maybe I could change the Teamwork Feats to also allow you to select from the Aquatic Prowess Feat list, in addition to normal Teamwork Feats?
What do you guys think? This is probably only going to get used for NPCs, so balance isn't completely necessary, but it's definitely a plus to be able to put it on the table for players as well.

I would ignore the aquatic prowess and favored terrain features altogether and instead give the archetype new animal foci that are aquatic animal themed.
This could be as simple as renaming the ones that exist and then have "One with the wild" apply to the animals associated with the new names. It might not work for all of them so some might have to be replaced.
For example wolf would translate easily to shark
Snake could become sea krait.
Bear becomes whale
Mouse becomes Clownfish
Owl becomes Ray
Tiger becomes Dolphin
A new one perhaps replacing Monkey could be Octopus, giving you a bonus to grapple checks. Stag could be replaced with Marlin which gives you a bonus to swim speed instead.
I like Threeshades' idea.
