Two things, with Grimlock in hand, Deathsaurus still seeming viable, but a little trickier. Potentially the leftover parts of an old fire phoenix from zoids as the Dino head replacement. getting the wings to move from spot to spot seems a stunt, partsforming may be the best bet. and Ion Scythe could potentially be given a gold undercoat as the Eaglebreast equivalent. Secondly, and this is kinda an off the wall idea. Rattrap or Packrat ala the Transmetals line could be made using Slug, of all things. The Transmetal headsculpt may be affixed in place of the head backpack, but visually they share mechanical detail, the hunched back, the torso shape.
