If you are able to, perhaps make Family Guy versions of the character models and re-inact scenes with their voice actors from the Star Wars Specials. Perhaps a Space Balls reference too, maybe on the Luke vs Vader fight in the Carbonite Chamber it could be "I see your Schwartz is as big as mine". Maybe if we go back to Robot Chicken, you could make a "Bonus Level" like with the end of the Dark Forces Duel" where it's an endless elevator and it changes your model to the emperor and stormtroopers are slowly moving down saying "M'lord" and you can reply back with a taunt that says "Stormtrooper" in different varying exasperated voices. Perhaps that would be a great way to do a credit scene at the end of the game with the credits coming down the side of the screen.
