Super Smash Bros. Ultimate Alts

It is heavily implied that every DLC update in Smash Ultimate will unveil a new element to the game. For example, Update 3.0.0 came with Stage Builder, online Mii sharing and Video Editor. A theory that I've had for a while is that one of these updates will increase the number of alternate costumes on many or all characters. For this potential update, I have created a wishlist of alternate costumes that I would like to see in the game.
