If by true Amerindian you mean the actual Amerindian cultures as we know them surviving to this day, it's not quite as hard as some people believe. It wasn't disease or simply being conquered that got rid of most aspects of their culture, it was the genocide the conquerors started upon the natives that really destroyed them. If for whatever reason the colonizing powers of OTL aren't as dead set on destroying everything it's easily possible.
The problem is in a number of places that genocide was something the actual people themselves did and the governments couldn't stop it, or it they'd tried they suffered politically. How do you change the drive for lebensraum?So you would just have to make the OTL colonizers more freindly to the natives and possibly start helping them then you would have amerindian cultures and large populations surviving to this day, maybe even a native nation-state or two.
Yeah, the actual Spanish authorities (well, the authorities in Spain anyways) were appalled by what was happening but there wasn't much they could actually do. Perhaps knocking off Cortez would do a lot to discourage more conquistadores if they heard about the army of a thousand men under his command who were completely slaughtered. Other than that it gets a little hard to come up with more ways to have more gentle relations. But there are precedents. The Jesuits were quite friendly and popular most places they went. Especially among the Guarani.The problem is in a number of places that genocide was something the actual people themselves did and the governments couldn't stop it, or it they'd tried they suffered politically.

What's "sustainable"? Anyhow, agriculture was present on the plains for centuries but after they were introduced to the horse they became far closer to the steppe-cultures of the old world within a century. So how do you get the proper draft animals to plow the soil without abandoning them for a more nomadic lifestyle?Amerindians on the northern plains and the South West have sustainable agriculture and a far larger populations. By the time the second wave of anglo settlers arrives in the south west and northern plains, the shock and awe factors are non existant. Amer indians have the numbers and the weapons to resist large scale settlement.
I'd say you could probably keep Western South America and the Greater Guarani areas completely native. Cortez fails, whenever some fool decides to attempt to attack the Inca(this invasion DOESN'T occur immediately after a Civil War, during negotiations where the Sapa Inca's army was essentially unarmed, and does NOT result in the Sapa Inca being captured. Divine intervention much?) and are repelled, the Inca begin to adapt. Believe it or not, the Chimu culture had a LONG tradition of metal working, and the Nazca had a long tradition of textiles. The Inca basically inherited these traits upon annexing these territories into the empire. It wouldn't be farfetched for the forges in Chan Chan to replicate some of the pieces of possibly captured weapons, especially a cannon, were the Spanish to be routed. Even better if they capture male and female horses. The Inca MAY be able to replicate gunpowder, with sufficient diligence. The Inca may posses archaic gunpowder weapons by the time another attempt rolls around that is more thoroughly curbstomped, resulting in another capture of technology, which the Inca again apply...
The Inca where a very adaptive people when it came to innovation. They were like Rome in that they basically took everything that one of their conquests did better than them and made it their own.
For NAmerica whe need to stop the Little Ice Age. Most of The Agricultural Centers in NA where wiped out by the LIA.So you need to make the native americans to start early agriculture everywhere.

Farming would ahve to yield a better lfestyle than a nomadic existance. For the Northeren plains, maybe the Canadians could get real upset about the abortive U.S. invasion of Canada. They then create a buffer of strong Native American tribes. With the urging of the Canadian government, Metis Canadians introduce draft animals, European farming techniques and equally important, modern weapons to the more sedentary tribes of Montana and the Dakotas. The farming concept then spreads to include some or many Lakota and northeren Cheyenne (they like the plentiful trade goods of the sedentary tribes and are tired of fighting for them).So how do you get the proper draft animals to plow the soil without abandoning them for a more nomadic lifestyle?
