I want Ganondorf to at least keep the important unique moves he had, which were his forward air and more importantly the best neutral A in the game--that electric jab that did like 7-8 damage. That thing's way too cool to get rid of it entirely.
Everything else can change and I wouldn't mind that much, even though Ganondorf was somewhere in my rotation of seven. Maybe create a new version of the stomp, since a move like that makes sense for a character who's imbued with the Triforce of Power, and the aerial backhand was also good. And if I had to change the forward smash for either Ganondorf or Captain Falcon, Captain Falcon would be the one to lose the elbow.
As for the other moves... up air, neutral air, up smash, down smash, up B, up tilt, forward tilt, down tilt, and probably down B seem too flexible for Ocarina of Time Ganondorf, and too hand-to-hand for Wind Waker Ganondorf. Forward B actually works for him, though. Neutral B makes sense, but it should still go just because the Falcon Punch must belong to the good Captain alone.
