considering how we're still going back and forth on ornithoscelida, I think there's plenty of room for a shake-up. Remember we STILL don't have any good transitional pterosaur fossils. I personally don't buy the scleromochlus-type ancestor hypothesis so there's plenty of room for variation. ESPECIALLY if we're courting the idea of silesaurs being early ornithischians, or whatever.
