Instead of a genderswap, could this be a case of role reversal?

Well, she did say "You´re going to be my wife"... but she looks too manly in her imagination to not be genderswap

I know this was drawn as a hilarious "What If...?" but being a hardened military woman literally from birth, I don't think Laura would even touch alcohol.

And Laura does look kinda masculine. You may just still be under the effects of the revealing of "Charles" true gender.

Chifuyu's hair is all wrong...

A male laura looks like sephiroth from final fantasy!
