To be fair, poppasketti states that it was a temporary clip to test out how they might look in motion, and wouldn’t reflect a final result.
Personally I’d be all right with a second bandolier (which is still different from how it looks in Solo) and greyed (or otherwise recolored) fur. Maybe he’s… Crunchbrakka or something. Goes by Crunchy.
JEDIT: Of course, his military rank would be Captain.
