The only major issue I could see in integrating the saucer sep into the galaxy x, is that the power systems running to the lance weapon could run through the sections of the ship that would be disconnected during the seperation sequence, so fesability on that isn't very good to say the least. But a better turn rate addition and another tac console would be sweet. My odyssey tac is pretty slow to maneuver, and these beasts are too.
