I'll reiterate that I feel the best solution for Broadside would be to reinterpret his jet mode as a small starship. Just replace the "cockpit" with a domed bridge full of little molded-in consoles.
I've also always felt that was a better option, too. Give me a Broadside that goes from robot to standard earth aircraft carrier to Cybertronian space battleship / starfighter carrier, like something you would see in the old Wing Commander games (for anyone that remembers those).
