As for multiple Death Stars, I still don't see the advantge of another Death Star in RotJ. If we're adding nothing to the plot and it's just in the background, then what's the point? Having the Death Star II at the beginning of ESB can at least imply that the 2 Death Stars were built simultaneously. If anything, a very early skeletal Dath Star might be best added to ANH somwhere, in the background of the earliest shots of the Death Star I. My main objective with the Death Stars is to remove the "out of nowhere" aspect of the DS2 from RotJ and make it appear as if the Empire had a plan for them that actually made some sense.
