OK, seriously, since most SW-games, like TFU, are supposed to be at least semi-serious, this idea was batshit-crazy.
However, the most amusing part of this to me was Lucas's reply...
Think for a moment: you're the father of a succesful franchise, affecting most of its stories and such. Your franchise has tended to be semi-serious, and you wish to maintain that in the new game. In comes a game developer, who suggests that the new game should have a growling and mumbling superhero-furball as the main character, who goes totally over the top and crazy with destruction.
In this context, what would a more normal person reply?
Probably along the lines of: "Dude, WTF? Are you high?"
And Lucas is more concerned with the lack of dialogue this would have lead to...
Tells something about Lucas, now doesn't it?
(not that it is a new discovery)
