Dress up as each other!
But do it so that you’re almost poking fun at each other.

Maybe give him some heels, or a large pair of extremely feminine panties to leave showing over pants somehow?

Just get wigs like each others hair, and maybe give yourself some facial hair if he has any.
Then try to act like each other all night.

Good Luck with whatever you decide

Here are some ideas

Cheerleader and a football player
Batman and cat-woman
