I have to say, the best Star Wars rules conversion I've seen is using the Frostgrave rules - the wizards as Sith/Jedi.......I think they all had a spell as standard to represent the saber, don't ask which as I don't know......the apprentice as a, well apprentice, and the general troops and weapons rebadged to a more universe appropriate title.
If I liked Star Wars (I'm not a fan generally), I'd have been all over that as it looked very very well done.
