Ok Redwing, I like some of your ideas, and don't like others. Personally, I don't like the idea of using a Time Warp/Portal thing. That makes it seem to me like we're delving too much into fantasy here, and straying significantly (as if the Time Matrix wasn't significantly straying) from Star Wars. I do really like the fourth idea, of being transported to another universe, because it's already been done, and it would give us more story opportunities. That's just my two cents though.
