I was interested to find Ady had given the idea of two Death Stars in the battle some thought, the second being the bare bones one from ROTS.

I love that idea, it really does give viewers of a special edition a WTF moment with Luke finding himself somewhere he (and the viewer) didn't expect to be.

And being so incomplete it would be much more plausible to imagine it being destroyed by a huge capital ship like the Executor destroying it by ramming into the thing.

The problem of the two Death Stars concept is that it would mean changing just about every line about "the Death Star" to something else, and we don't have enough Akbar or Mon Mothma dialog for it.

I think a frame-structure would be harder to be destroyed by the Executor, the frame would probably just fall apart rather than explode if it gets hit.

And having it go through a bunch of empty space to reach the core would look weird ;)
