I would want:
Scrubs (Each doctor could come with a paitent!)
Invader Zim (Although due to their very large heads and Gir being soo small this would be hard to do)
Heroes (A brilliant, already suggested idea)
Super Smash Bros (Infinite possibilities, with massive characters like Mario, Sonic, Samus, Kirby, Pokemon.etc attached to that lisence)
Yaaay.
