It's possible that since Dracorex is almost defintely a young P. wyomingensis that the head dome thing could be removed on baby pachys, although the devs don't think it looks good on the current model. If Stygi isn't its own genus then it's still a different Pachycephalosaurus species than P. wyomingensis (P. spinifer), so nothing would come from that.
