A full swap?

I know the title is a bit...weird but what if we had an event where killers became survivors and survivors became killers? Now I don't mean that we have 4 killers running around I mean like we have a killer version or perhaps a costume swaps for both killer and survivors.

Like perhaps Corrupted Jake where he is a costume swap of perhaps the Trapper or whatever have you. Now on a side note I'd find it funny if we had such outfits and the thought of a killer working on a gen be pretty hilarious. Also on that note imagine if killers were the survivors like picture it their abilities and having to work on a Gen while a Meg goes hunting for them with a flashlight.
