She's a cool character. But she has gotten great character treatment in The Clone Wars. I'm not sure we really "need" more in any format. I'm not against it. I'm just saying I don't see the need.
Going back to Boba Fett, that really is an interesting case. There is no real reason he should have been so popular, other than George decreed it. I remember the hype way back even before Empire was released, and he was a limited edition action figure that you could ONLY get by mailing in so many proofs of purchase from other action figures. Nobody knew ANYTHING about the character at that point. But he was suddenly mysterious and cool just because he was advertised as being mysterious and cool. Then Empire came out sometime later, and we were prepared for him to be mysterious and cool. And since he didn't say or do anything to detract from that, he was still mysterious and cool. Then ROTJ, where there really isn't any need for him to appear, but he is there. ...and doesn't really do anything other than fail to recognize Lando, fail to shoot any good guys despite that Luke is the only one with a weapon, and then fall into a sarlaac pit.
As far as rebooting, hard to say. I really don't see the need or benefit. It seems like there is FAR more potential risk than reward. But that has never stopped studios in the past, so...
But what they really SHOULD do is a Bluray release of the original trilogy in their original versions, with only effects cleanups and no additional/changed scenes.
