Maybe they could give us a cosmetic choice, like glamour for our summon pet and we can make it Carby by using an item or something. Heck even do this with Eos and Selene, turn them into Carby's.... Seriously Carby has been support in the past.

Though on another note. Egis/Pixies seem to always get hit by landslide and recover because they hover. How would Carby survive?
