Not as inconceivable as some might think . . . During the American Civil War, while we were otherwise engaged, the French were invading Mexico. Contrary to what many think, thats where the "Cinco de Mayo" battle came from.
I've built models of USS Arizona in the configuration of 'if she had survived Pearl Harbor', so we are all subject to the vagaries of fate and the unknown . . .
Anything is possible, especially if a sense of imagination is permitted access.
Go for it !!!
