I honestly don't know why people are so concerned about using models from other games. For one thing, the public has a "fair use" provision when it comes to copyrighted content which I believe this would be included in, and secondly this isn't a commercial venture, and it's clearly created by fans for fans and not directly competing with other Lucasarts products so there isn't really much for the copyright owners to be upset about.
And besides, even if I'm wrong, using art from another game and using a likeness from the movies or EU are equally a breach of copyright.
Edit: Hell, using the term "Star Wars" is basically a breach of copyright.
