Well, speaking for myself, I'd really like to see the rest of the Monsterbots done in deluxe Titans Return form. And then have them used as remolds for the Decepticon Headmaster Junior/1988 Headmaster form.

Repugnus remold into Squeezeplay.

Grotusque into Fangry, possibly Horri-Bull as well. Alternately a Horri-Bull mold could be used for a different character/different characters - say a Snarler, with a Wolfwire redeco/remold into Carnivac.
