I know at Gen Con, FFG had a demo xwing game that took place on the surface of the death star. The rebels had to take out a number of gun turents on the death star to clear a path to make the trench run. They had the table set up like the death star surface and had turrents on them.
Will FFG put out rules for the turrents? How about a death star surface expansion with what they had at Gen Con for a play area with the turrents?
