I don't really care about Evil Teams anymore, they are barely a threat since they overuse weak common pokemons.
I think we'll get southern France if we're sticking to Europe, not that France didn't have it's own religious wars in the past. I wouldn't mind seeing another team try to take over the central authority of the region. N (briefly) became that according to Ghetsis in BW.Seeing as this region will be placed in Spain or Italy, both have had religious strife. It is quite possible our region's teams will be two different religion extremist groups who constantly go at ends with each other, both of them wanting control of the government. Alternatively, we might get a team who wants to keep control of the government while the revolutionary one will fail to take it over in Sun, and take it over in Moon.

I have no geographic degree, but I'm pretty sure France doesn't have any tropical/semitropical-ish areas like one of the towns in the concept-art. Spain or Italy would make sense in my opinion tbh.
