I think I have a way that could work. I feel like our regions have different themes, but we could make it so that it's like Alola, where it has multiple islands in the region, one for Gashi and one for Canoa so they can still be a region together but still semi-separate and have the original themes. Perhaps if we did make a game out of it/them the player could choose which island to start on, and that would change which starters they could pick, the ones for Canoa or the ones for Gashi.
