Of course. But lets see the whole picture if we talk about recognition...
- If we talk about units for civs like Mapuche, Sioux and lets add the Comanche is because they have notorious mounted units from seminomadic to nomadic cultures from the Americas. The Sioux and Lakota in the popular imaginary are traditional users of lance, axe and bow as much as guns, just remember the image of the Lakota lance decorated with feathers and leather.
These native civs with raider units could overlap between them, but would not overlap with modern native infantry.
- Mapuche is likely to cede their slot, not only to a nomadic NA native civ, but also to exchange between Southern and Northern SA the Colonial and Native roles. So we can have Muisca+Argentina instead of Mapuche+Colombia.
These take us to the situation were we have at least Aztec, Maya, Muisca and Inca all with infantry using stone to bronze weapons. Could not a modern native infantry add variety to the region? Mainly when Aztec and Inca units are actually iconic.
Maya civ in game is mostly the native american science civ, their leader, abilities and buildings are good enough to portrait their popular picture. The unit could be a chance for a novel element from their recent history. People would not stop buying any CIV dlc just because Maya civ dont have the generic looking shirtless and feathers in the head warrior that they associate with Maya, this is not a Jaguar or Eagle warrior situation. Neither Firaxis will get the "controversy" from the "outside of the box" selection of leaders for civs like the Netherlands, that to be honest was barely polemic anyway.
