How would that work?
Besides everything we need to know about Luke, his frustrated wish to leave the farm, his idle friends and even who Biggs is, is already in the film so all that would be added would be some low quality unfinished scenes of some people we hardly get to know at the expense of important information about two major characters.
Answers please on the After Ady thread because if it can be made to work it won't be in ANH:R.
