Has it been done? Haven't found out anything. A mod representing mesoamerica with a Spanish Invasion as end game event, would be very sweet.
EDIT: This might be it, however I'm not bilingual so I have no idea as to what it says. http://www.mundusbellicus.fr/forum/grande-stratégie/crusader-kings-ii/mods-modding-ad/8714-apocalypto-a-native-american-mod
I can't French, but by looking at those screenshots it sure looks interesting. If any one knows the language they are more than welcome to translate it.
Silly me. There's a link there that take you to the CK2 mod forum that's in English. As I recalled, it isn't complete, but It might be playable on an older patch.

I can read french with my Spanish and Portuguese, the mod is what you would expect it to be.I can't French, but by looking at those screenshots it sure looks interesting. If any one knows the language they are more than welcome to translate it.
While not feudal in itself, relations were very personal and there was a complex tributary system which i believe would be better represented in CK2. Plus we already have tribe and horde mechanics which i think with some development could work well in the area.
