I think the Castilians dominated and controlled ties with Spanish America even to the exclusion of Aragonese to a great extent, much less Austrians, Netherlanders, Milanese, Neapolitans, Sicilians, Franche Comte-ans, Hither Austrians, Bohemians and Hungarians.
Is there any plausible way for the American conquests to be made to some extent and then ruled as common property of the Habsburg menagerie, with Castille not being necessarily most dominant in all parts of it in the decades down the line?
