I think Lego would try to re-release the old Classic Space Galaxy Explorer first as it would be more sentimental to many. The fact that they haven't tried that yet, makes it less likely they would try the castle first.
If LEGO did this I would be very happy.
This was probably the only set that could come close to equaling the Yellow Castle in my humble opinion, mind you.
