If you want magic i would say go with Either Dragonstar (A game i have raided to get SW stuff, take the magic out and smugglers run source book is pretty handy for doing Fringe Campaigns). It really incorparates Magic and Space, and does a really good job i think of putting D&D in space. Which SW is not, there are a decent number of source books out there for it, and from what i read it is not a bad campaing universe, the biggest problem is FFG doesn't really support it anymore.
D20 future and Modern can also work pretty nicely, you will have to do more work making your own campaing world, but there are a few source books for campaingns out there i forget the names but i know i have seen them. And they are even putting out a post Apoc book i think in a few months, it may help or have ideas.
Old Alternity could actually work i have been raiding that too for SW stuff the systems are Close and it would take some conversion but it could be done.
Me using FL for SW
On that note, I really like Pinnacle's triangular format for those more than the simple, two-sided sandwich fold kind.
