nemi: If you can get the level under 2 minutes it could be worth it. I forget how long the secret star is in comparison to the normal star, but if it can be done under two minutes it could be good. The trouble is that the comet medal would unlock the really short boulder bowl comet, but then that would force you to do the shortcut with rock mario, which doesn't seem very reliable. However, it sounds like a good idea for segmented.
UchihaSasuke: You need rock mario for the boss and to get a goomba for the secret star IIRC.
