I've always dreamed about the Thrawn Trilogy being made into films. To be honest though, even though generally I'm not a big fan of CGI, today a film like this would be like 90% CGI anyway, so I'd love to see it made with the original cast using performance capture, Beowulf style but better CGI. They'd have to do something about Carrie Fisher's voice though :-D
Oh and Bryce Dallas Howard would make an excellent Mara.
