I doubt it. It’s probably just a quick cameo to set up the Smash Bros. movie.

I think it could be more than a just a quick cameo because they got Glen Powell to voice the character, he's one of the bigger up and coming stars in Hollywood, I suspect he has maybe not quite as big of a role as DK in the first one, but not a tiny role either. 

It would be foolish to hype up a character like that when he has little screentime. Sadly it's happened with Disney (the pig in Moana getting upstaged by a brainless chicken) and I think it must have happened with Illumination too.
