Scenario: The Trek version of the Milky Way collides with the Star Wars Galaxy, merging the two with a freak occurrence where most of the habitable planets actually survive (with the exception anything near the center of the galaxies, as the two super black holes would merge - essentially eliminating Byss). Trek time line is just post-Nemesis and the Empire is at it's height (5 to 0 BYY).
Traditional Hyperspace routes are out of whack due to the galactic merger. Civilian and Military transportation is disrupted on an interstellar scale. While the Empire is technologically superior, it is suddenly fighting multi-front conflicts Galaxy wide. The sudden disruption of the logistical supply train puts a greater strain on the Empire, while the Rebel Alliance is finding new support from the ST worlds (although all they can offer at first is extra manpower, as their infrastructure would need to be overhauled). Basically, it's all one big mess that one way or another will take years to sort out. At least the Empire still has the first Death Star
