I Could see Chile in a confederate union with Peru OR Argentina with only minors problems.
But Chile without Valdivia and Chiloe? it´s almost impossible, until 1826 these places were the last bastion of the Spanish Crown in Chile. The conquest of these territories was fundamental to ensure Chile and Argentina Independence, so the Second thing a independent Chile does (the first is: https://en.wikipedia.org/wiki/Liberating_Expedition_of_Peru) is the conquest of the island.
The island never was proper Mapuche Territory and was Part of the Spanish Territory from 1567 onward, well before the Colonial period of Chile(Circa 1600-1800) so the maps were Chile don´t have the island are a little bizarre for my taste.
The same with the City of Valdivia Founded in 1552 by Pedro de Valdivia, Destroyed in 1599 and Build Again in 1645, was of fundamental importance on the defense as the southern most enclave of the Virreinato del Peru, from there the Spanish attack the Mapuche Territory, and most of the land south of Valdivia and the Calle Calle River was considered "pacified" with a "camino real" Build in 1784 to connect the city of Valdivia with Chiloe and foment the settlement of the zone. Valdivia was conquered from Spain to Chile in 1820, there is no way Chile don´t have at least OTL Regions of Los Rios y Los Lagos.
As this is the situation i also see little possibility to be a a Independent Mapuche country in the Biobio and Araucania Territories, especially beacuses is surrounded with a country that is cut in half by these terrritories
The Patagonia could or not be Chilean Territories
