Abraham Lincoln. I would love to play as Abraham Lincoln in a Super Smash Bros. game.
If it's gotta be something from another game, though, I'm gonna go with Cecil from Final Fantasy IV. He could use a Zelda/Shiek, Samus/Z-Suit Samus style switching system to "Class Change" between a Dark Knight and a Paladin. The Dark Knight would have very powerful attacks, but would damage himself when using "B" specials. The Paladin would be less powerful, physically, but his specials could potentially be much more damaging, and safer to use besides.
FFIV was remade for the DS not too long ago, so I'm holding out hope that this could actually happen.
