Is it possible that marve and dc characters join together?

the two companies have already made a comic and game about it and Marvel and Warner bro. studios are thinking of making a movie.By the way, the two universes not only met but mixed together to make a third universe with mixtures of marvel and DC characters like, "Super solder" a mix of super man and captain america and my personal favorite, "Speed Demon" a mix of ghost rider and the flash.
