Honestly, It should be fairly easy to completely copy Super Mario World if Media Molecule did it's job right.
Well outside of sackboy and the like... etc.
As cute as Sackboy is it's really going to bother me that you HAVE to make the sackboy the main character. Seems like that screws with a lot of the other genres and stuff you could do with a more open game. All a matter of seeing though.
