This is a nice idea IMHO. Doing a 3-in-1 edit with older Obi-wan telling Luke what happened and some voice over during the movie. If you could get someone who has a similar voice to Alec Guinness, you could get only the most interesting parts of the 3 movies and have a really nice story that doesn’t contradict what is said in the original trilogy. This can be the best approach to really turn those awful movies into something that we all can enjoy. 😃

Looking forward to see how your edit goes.
