On second thought it might be interesting to have a more fragmentary/dubious Ceratopsian, such as Notoceratops or Serendipaceratops, for the purpose of putting opposable digits on the hands and feet, being more adapted for climbing, like those of a Koala, Possum, Chameleon or Monkey. Realistically Serendipaceratops might not be the prime choice due to it's ulna not being very curved forward, though some ancient climbers do have fairly straight ulnas by the looks anyway.Likewise for the the Ceratopsians, unless you want to argue for a Microceratus-like animal that can climb the pole.
