Everyone on this forum, except for the trace amount of Spanish members not from Barcelona, screws Spain over in whatever way they can, and loves the French. It's an extreme cliche. I can't think of an alternate history cliche more prevalent than a fallen or semi-fallen Spain.
The one nation I do always wank on these is the Ottoman Empire, because I like the idea of a united peaceful Middle East.
But actually go ahead and give Occitania Catalonia. But just Catalonia proper, nothing of the rest of the historical Kingdom of Aragon.
a fair compromise
EDIT: The frenchies could have occupied it during the ATL Spanish Civil War
