I'm not one of the devs or mods, so I can't really do anything about that. You could ask them on the Discord channel but for me, it would be nice if we're trying to implement a Unova/Alola/Kalos/Galar setting type of game with the Moemon (though Galar seems out of the question for now) or maybe a new setting altogether. Though the major problem here is how to handle sprite updates when they come out and if the devs and mods will allow such a game without their consent. Now that it's possible to make a bigger hack through UPS, that could also be an option as well.
