Kirby and Jigglypuff could be a pair.

Maybe having Popo and Nana as a pair could work (if you can't find separate 3D images of them, you can just pair the two with Wolf like in the previous games).

Who knows? Maybe Captain Falcon and Ganondorf could be paired with each other (they are unintentional clones, after all).
