Can you imagine how amazing it would be if Bruce Boxleitner was in Episode VII as a New Republic General? All I would have to know was that he'd been cast and then all my worries about the new Trilogy would be swept away!

Having now seen Babylon 5, I can't help but to agree 100%.

Oh, and on that note ...

I totally want to see Mira Furlan in Episode VIII/IX. She should be cast as a villainess, though, rather than a heroine, just to make her hypothetical character as distinct from Delenn as possible.

While we're at it, cast Patricia Tallman, too.

I think she'd make for a good lady smuggler. Hell, she could be Mara Jade herself!
