Just a thought- what chance is there of some Renegade Ops representation? I know it's probably not the first thing that come to mind when you think of a SEGA ip, but if the Bonanza Brothers can make the cut, then why not? It'd make some sense too, as the characters all have their own vehicles and special moves (Diz's EMP, Roxy's air strike etc.) and in several levels you need to fly a helicopter as well. Add in a hovercraft for the water sections and you're good to go.
