Have you read Julian Cranberry's book The Americas That Might Have Been? It sounds like it might be interesting in that connection.

I'm considering designing languages based on an uchronia when
Europeans decide not to discover America and then the territory of the
continent's area is progressively divided by states that arise there.
Maybe the expansionism of the pre-existing states (Aztec, Inca, etc.)
would inspire-force many tribes to join into other ones to defend

But maybe if I take a look at conlangs that possibly already exist and
are based on a similar idea, I'll be satisfied and get this idea out
of my head. Do you know any uchronlangs like what I described?

Até mais!
