Yeah, "he's similar to Combat Hero OP" is just all the more reason to make a new mold (the Volvo OP comes close) now that can be pretooled as one or the other, as is the current practice with molds anyway. Sacrifice the powerlinking, make it pre-Spark of Combination Rodimus, whatever. Tooling for two heads and chestplates (Rodimus can get away with the side-ab tires; CHOP can get away with the boosters, or make them 5mm guns). Could come with a version of CHOP's air-launch rocket/s (and stickers to relabel him Sureshot), or Rodimus' Galvatron-esque cannon and symbol flag. There are even redecos for either built in, in blue CHOP and Checkpoint.
