The only problem I can foresee is that as Ady's skills improve by the time we get to see ROTS:R it will look so amazing that he will have to begin again from scratch with ANH:R:R (by which time we will be watching everything in 8D).
It will however be a great way of becoming a one man Hollywood studio.
By the end of the Revisted cycle Adywan Prods will be able to tell just about any story (not just Episodes VII through to IX).
