How is the model swap NOT going to change his hitboxes? You do realize why the hitboxes change if you were to make Paper Mario an alt of G&W (which doesn't make sense in the first place, but whatever, we'll run with it for argument's sake), right? Hitboxes have to fit the size and shape of the character it belongs to, and since Paper Mario and G&W are obviously different in both of those manner, the hitboxes would have to change in order to fit the model swap. I think that's what you aren't getting, there's no way to make PM an alt of G&W without changing his hitboxes
