This might have already been listed (and if it is, I'm sorry):
Maria Theresia and Carlos III of Spain.
Both great Catholic rulers in their own right, they could have been *the* Catholic co-rulers of the 18th century, and recreated the Habsburg empire (assuming Carlos could get elected as the HRE). They would definitely have a huge family and it'd be interesting to see what changed in history thanks to their kids.
(Also, I never thought Francis was good enough for Maria Theresia, and I feel like Carlos would be the husband she deserved)
Would this be a Carlos who rules Naples and Sicily as well?
