Busted relay would do the job - a wormhole could as well. Either or, Joker will not be happy. I can't see Shepard risking their crew just to jump on board the Death Star for a tour though. Would probably be better if they ended up in the same region as the Enterprise, then at least the 2 Captains could talk stuff out. Maybe then a dashing rescue for Princess Leia could ensue.
