Not really sure. Obviously you can't commercialize it, the only one who can is George Lucas himself. (Extreme exceptions, such as similarly named people, but even then they have to prove they are not cashing in on Lucas' fame).
So all you are looking for is traffic-related hits, which just isn't happenin' nowadays. Personally, I don't want anything to do with a domain which can be snagged for trademark violation at any time.
You MAY try Lucas himself, but if he says no, then you may be in the same jam as before.
