I find your last idea in particular quite interesting with the force lightning. It still leaves some room for confusion and uncertainty though, as we don't have any indication that Vader was ever Obi-Wan's apprentice, nor why he has a bitter hatred of him at the end fight. Technically speaking it would take a very talented CGI man and some actor in a costume to pull it off, but it sounds promising. I still feel that it would be nice to be able to watch the movies 1-6 and not have the Vader/Anakin surprise spoiled, but that may not be possible to pull off effectively.

Hey, yeah it would require a lot of editing, not sure it will ever happen but suppose depends what Ady has up his sleeve for his prequel edits. It does seem a shame to me that the whole shock of "I am your father"is taken away if watched 1-6. Before the PT, I had always imagined Anakin confronting the Emporer and getting his ass kicked from the aforementioned Yoda quote. I also think it would be much cooler if Mace is about to kill the Emporer and Vader deliberately and knowingly saves him.

One of my issues with the PT is the need to explain everything; i.e. do we really need to see the moment Anakin falls or becomes Vader? Anyway back to your point does Obi-Wan's comment about Darth Vader being his apprentice need to be explained in RotS? Tp me it's always seemed Obi-Wan is trying to spare Lukes feelings, and Obi-Wan knows who Vader is. With regards Vaders hate; what, if Vader (in suit) still had his arms and legs cut off and Obi-Wan leaves him on the shore of Mustafa; a lot of that dialogue I think needs to be cut in any case to make the father reveal later a shock.
