The radio drama adaptations are probably the closest we’ll ever get to what an “extended edition” of the trilogy would be like. It’s a neat concept to imagine those in movie form, but ultimately, the films are better off in their trimmed down state. ANH, in particular, is a very tightly paced film (except for the Jabba scene), and does an amazing job of telling a strong story in under 2 hours. Adding a lot of previously scrapped content into the film would likely only make it less effective.
