A side thought: since Catherine of Aragon was Charles V's aunt, England could have become part of the Habsburgs empire. One of the family politic was to intermarry the several familiy branch in order to keep their possessions united.
If the hypothetical son of Catherine married a cousin, you could have an Habsburg empire covering large part of Europe...
Guess that the French kings would become quite paranoid
