 they should just make a Smash Kart.

With Link, Villager, and Isabelle now in MK8, it's already happened. :p

But what if everyone had their own items, stages, and karts! I know it is already happening but not to the scale that I desire. I want Samus, Kirby, etc and their music and stages. It'll never happen though.

Hey don't give up hope; Nintendo's character and franchise crossovers are getting more and more extensive this gen, I wouldn't be surprised if in the future it all becomes a big melting pot.
