Nintendo/Blizzard Crossover?

I come today to propose the next possible option for a smash fighter. Within recent time, we have gotten Diablo 3 for the Nintendo Switch, which is absolutely fantastic for all us dungeon crawler fans. We also got a Ganondorf cosmetic set in Diablo 3, but nothing in a Nintendo game. But I must ask now, will we get anything special coming to our favorite fighting game of recent time? I propose a Diablo 3, Super Smash Bros crossover, bringing a beloved character from the D3 universe to smash. Here are a few ideas, that are loose enough to be changed in any fashion desired.

\-Diablo Himself, a heavy class fighter with fire and demon themed abilities

\-Cain, a light class fighter, focused around his relevance to lore and knowledge, likely a ranged attacker

\-Tyrael, a medium class fighter, with angelic and hard-hitting melee abilities

Am I the only one who would love to see this become a thing? I personally would be super excited to see Diablo and Bowser duke it out, two titans of their own games, in size and strength. It would be a welcomed entry to the series for any blizzard fan, and maybe even bring in some more people from the blizzard fanbase to Smash Ultimate. Your thoughts on the idea?
