a bit like the classic Q: 'Where's your Homework?' A: Oh....um....er....the dog ate it!'
but seriously, I think the main aim of an fan-edit of the classic trilogy should be to try and undo any of the damage George has done on his subsequent revisions, so I'm all for seeing Sebastian Shaw back as jedi spirit, and not a weird morph of Hayden and Shaw.
Or perhaps remove Anakin completely from the scene, as according to ROTS Anakin shouldn't have learnt how to become 'one' with the force anyway, unless Qui Gon appeared to Darth Vader before he died and taught him how. (now that really would be an interesting scene!)
