I think its a mechanic that could work
The Native civs that do not have revolution could just have a Tupac Revolt button, just as revolution that would turn their vils and units into other units (this would be obviously temporary)
Inca - Tupac Revolt
Aztec - Tlaxcalan Revolt (it would turn Azzys units into Conquistadors, Musketeer, skirms Lancers and light cannons).
Lakota - maybe @AnaWinters could help in this matter
Hauds - also not familiar with their history or revolt
The Asian Civs could have a Revolt/Revolution in the same sense that there are european revolutions, but with only one option and a special deck
Chinese - Boxer Rebellion (all vills turn into legendary rattan shields. All villages and TCs spawn irregulars and sentries - like brasilians voluntários da pátria - Monks get limitless disciples and disciples become even better)
Japan - Meiji Restoration (Converts japanese units into european ones Gatling Guns, Falconets and Musketers and Skirms and Hussar/Dragoon)
India - Independence war (all vils become conscript sepoys - a type of revolutionary), Sepoys could have a card for a grenade attack (like peruvian legion) also with one factory card and HC.
