Definitely, haha. If the forest was its own set I think I'd do something like:

King - Dragon (this would be pretty tough without shrinking him way down or just doing the head or something...)
Queen - Hildebear
Bishop - Booma (go with the classic? Could go full-on Gigobooma)
Knight - Wolf
Rook - Monest (maybe with the mothmants around but that might be too much)
Pawn - Rag Rappy
