I don't know that it would make much sense to do that, except in terms of taking the entire d6 system, and just changing the setting. You'd have to work on how to match damage potentials of Force-users to others in a world without blasters, but other than that, there's no system-reason I can think of why you couldn't do that.
Essentially, that's what D6 Fantasy does...
Which, since it's free, is a fair download at DTRPG... why reinvent the wheel when you can use one aready done?
