I like pretty much all of the cosmetic stuff here, like giving his black and white alt back, better taunts and poses, and extra songs and spirits. Some of the moves are good, like swapping the chomp for a shaky grab, giving him some more visceral throws, and the earthquake punch for down smash.
That said some of the changes feel a little overkill? The up smash uppercut has too much overlap with forward smash for me to prefer it to his headbutt, and I don't think every move needs to be a reference so the jetpack change also strikes me as somewhat unnecessary. Not sure how I feel about him still having the waft either. It is iconic... for better and for worse.
The stage idea is pretty interesting, I think a "Great Cave Offense" style of giant, explorative level would be a fun direction for a Land-inspired stage.
