AHC: Multiple indigenous states in the Americas

Is it possible for more than one indigenous state to survive or reform in the Americas? I know Chan Santa Cruz had surprisingly good chances of survival, but are there other places in the Americas where indigenous states could survive to the present(for instance, could the Mapuche have stayed independent) or else European states become throughly indigenized(not necessarily wholesale removal, but certainly the elites are native or strongly pushed to identify as such, or both) and how would it affect U.S. American attitudes towards natives?
