If they just inserted Yes Man from Fallout New Vegas without any sort of buildup, plot relevance, or explanation I would... be pretty okay with that.
Would it be Phil Skywalker or Luke Moscowitz? "Good Afternoon. I am the Grand Exalted High Majah of Earth, a non-existent but real sounding planet." "Uh huh . . . ." "Yes, we're on a waiting list. As soon as there's an opening on the galactic map, we're next."
How about Anakin Moskowitz? "He's got Kraytman's lightsaber! The power cells are dead!" "No power? Ah, but if all of you in the audience who believe in the Force will clap your hands, my lightsaber will be magically recharged!"
