it would be tricky to pull it off. the characters are from different game, so art style and size is already somewhat different. and I don't know how would the world looked like for a Smash warriors game.
Hyrule Warriors is fine since it is from the Zelda game. but for Smash, which one would you pick or how, you wanted to put a warriors game with different character designs to a campaign mode that is irrelevant to each other.
good idea, but it would be hard to properly execute it.
