I don't think they should simply transplant the Smash Bros roster into Mario Kart. I suppose they could have a few guest characters or something, like Kirby. Mario Kart has its own history and traditions.
Like it or not, the babies aren't going anywhere. Kart (E) has a much broader demographic than Smash (T). I assume the babies are popular choices for younger players.
Common Mario enemies like Koopa Troopa and Shy Guy are series mainstays as well. You'd never see a regular Lakitu playable in Smash Bros.
I don't doubt that the Kart roster will continue to grow and expand, but for the most part, it will do so within the Mario universe.
