I will admit, I do not know a whole lot about the Spanish American Wars of Independence but please bare with me: What if, shortly after or during a more or less OTL path to independence in Spanish America, the liberated states remain tied together in something not too centralized, such as in a single state, as this would be too fragile and thus doomed to be short-lived for such a vast and diverse area as Hispanic America, nor too loose, as in an ineffective confederacy that would probably end up more symbolic than functional (like OTL's UN) but rather united in some sort of supranational union, like the contemporary, OTL EU? How could this be made to work and what would the effects be?
