I like the continuity problems, like first it's Ensign Ro, then it's Wesley Crusher in the purple uniform, then it's Wesley Crusher in a different uniform, then it's suddenly widescreen footage from a movie. Seriously though, well done putting together footage that works fairly well.
However, consider that Star Wars takes place a long time ago in a galaxy far, far away. The Enterprise generally can't travel to other galaxy, let alone galaxies that are far, far away. Also, let's not forget that Star Trek takes place several centuries in the future, so that period of Star Wars would have long since passed.
Unless they travelled through time.
