I doubt it ever will. SCUMM Revisited was always intended to be an explorer for SCUMM games. The additional game support was mainly there because it was a simple thing to do (because the formats were related). Not so for JK2 as far as I'm aware (although I haven't looked at the files). Also, I'm sure it'll be rippable very soon (if it isn't already) - since the Star Wars games have always had a much larger "hacking" following than the SCUMM ditto. And, finally, 99%, if not all, of the music in JK2 is taken from the movie soundtracks. Why rip it in inferior (although not much from what I've heard) quality when it's so easy to get?
