I'd like to see the Who's Line Is It Anyway regulars do it. I'd bet they'd kill.
But the premise of this one is slightly different.They did it on many episodes of Who's Line. I assumed this show was based off of their regular skit...
One of them was told which superhero they were and what crisis the world was facing, and then they had to come up with a superhero name for the next 3 people who joined the skit. They always said "Thank God you're here..." before coming up with an absurd name like "Potato-peeling boy." Together they'd find some way that all of their absurd powers would fix the crisis.
