Evil Super Smash Brothers

I've always been fascinated with the idea of games from the point of the view of the villain. I'll bring up more on this later, but for now I'm wondering if anyone else would like to see a Super Smash Brothers (or possibly a 2-d version like Street Fighter) but made up of all villains.

Here's some characters I think should be included:

1. Bowser aka King Koopa from Mario Brothers series
2. Gannon from Zelda series
3. Wario from Mario Brothers series
4. Wolf O'Donnell aka Star Wolf from Star Fox series
5. Ridley from Metroid series
6. Dracula from Castlevania series
7. M. Bison from Street Fighter series

more...?
