Hah, I had the same idea about the deathstar surface! But when thinking about size and detail, it already gave me an headache, how big should it be and what would be too big? How much detail? And biggest concern is: The UHU X-Wing is with a cutaway look into it, so it doesn't really fit to show it in action.
Second idea was to create an ellevated stand, like a maintenance plattform. Give it some realistic scene to stand in, maybe even some LED lightning. Easier to build, less distraction from the model and more fitting, at least for UHU's X-Wing.
Something like this, but with paper:
