I just had a thought in the DLC of a pokémon Scarlet and Violet white striped bassculin and a historical/hisuian growlite appear in kitakami where klevor and historical/hisuian quilfish appear blueberry academy and while blueberry academy is in unova in game you could instead have it in kitakami Heck, you can't even make it so that those variant species did not go extinct in those areas and that's why they exist in those regions
