I was thinking something along those lines when the idea of putting it into ROTJ came into my head, it's very dark (persumably to hide the lack of a set) even in that mock up I had to fiddle with a lot of wonky matte elements and remove some nasty red shadows.
I would be interested on how you would make a small gun interior both for this thread and the After Ady ANH one.
As I said it's all over the place in terms of vagueness as to where that place is and where all the elements sit.
