I know what a "what if" is. But in this case, it wouldn't be a matter of the character choosing B instead of A (like most "what if"s are based around) but it would be a complete rewriting of the character from ground zero.
And things like SE
being a closet mutant completely rewrites Joe history in such a way that it would be integrating the mutants from the very beginning as part of government operations.
Which then gets into rewriting the X-Mens history and goes into the idea that if there are mutants and some are already working for the government, then why have a group of "normal" soldiers in the first place and instead make a unit of enhanced soldiers.
So if you want to make any of the Joes into closet mutants, then it opens up a larger can of worms that takes it beyond the simple Joe/X-Men crossover.
