Other than both being set primarily in space and the necessary use of spaceships, Star Wars and Star Trek really don't have that much in common. Certainly the technology is totally different, and the mental powers of Vulcans, Ocampans, etc. are in no way similar to the Force. Plus a major source of conflict in SW is the whole "light side/dark side" split and that definitely wouldn't fit into the Star Trek universe.
If you had to twist Star Wars to shoehorn it into the Star Trek universe, then it really wouldn't be Star Wars anymore.
You mean the Terran Empire is not the Dark Side?
