In 1783, the Spanish PM Count of Aranda predicted that the USA would not only survive, but thrive, become a great empire of its own, expand across North America and inspire the spanish colonies to become independent. As such, he suggested to King Charles III to divide the colonies between his sons and turn them into different kingdoms that would be tied in a web of alliances and look up to their Spanish counterpart as their superior, who would take the title of Emperor, with only the islands retained under direct Spanish leadership - 80 years before the first British dominions.
The King responded that Aranda was exaggerating and that this kind of reforms was not needed. A century later, Spain only controlled the insular parts of its American empire, and soon after lost them to the Americans.
So, What if King Charles followed his PMs advice and divide the Spanish Colonies in different kingdoms with their own national identities that would be under Spain's sphere of influence?
What would these kingdoms be called? Would this lead to a different scenario in the upcoming French Revolution? Would it allow Spain to retain the title of Great Power?
