What if, due to whatever succession of factors (less successful Bandeirantes? Portugal gets involved in the 18th century continental European wars and gets a handing over of its own ass?) the 1750 Treaty of Madrid set up to demarcate the borders between the Spanish and Portuguese empires had yielded more favorable results for Spain in South America, primarily in what would become southern Brazil? I'm thinking of a consolidation of Spanish control over all of OTL's three southernmost Brazilian states (Rio Grande do Sul, Santa Catarina, and my home state of Paraná), portions to the south of Mato Grosso (roughly corresponding to most of OTL's Mato Grosso do Sul), and... perhaps chunks of São Paulo? The maximum i can see is the Tietê river, Spanish control over the city of São Paulo itself would already be way too much.
What would be the effects of Spanish control over all these new territories? This could be the foundation for some sort of Paraguay-wank, with the region's center of gravity shifted further eastward as it now has a coastline. Would the Banda Oriental (Uruguay) be added to this administrative entity?
What happens to Portuguese Brazil, now that it's been reduced in size?
