How would (You) go about designing the next Smash Bros game if you were in charge? Would you make it Ultimate Deluxe? Or would you try something new?

I just want Sakurai (or whoever takes over for him since he's working on Air Riders) to fix the old characters. Most of them need heavy reworks if only to better represent their home series. Especially Wario, Young/Toon Link, Ganondorf, Kirby, Dedede, and the entire Fire Emblem roster other than Marth and Ike
