W/E happens don't panic...
I would not be opposed to this actually...so long as they actually nerf some of the AT's since some of them have close to 1 hit kills...If I were directing smash 5, I would implement a mechanic that would allow you to choose an assist on the CSS that you could summon after filling a meter, kind of like in MvC.
I think it'd be a cool mechanic, and I think it'd make being an assist a better consolation prize for those who wanted the character playable.
