SSWR:"Angel, those pics of 3PO in Jabbas palace are stunning! It's feels more like ESB as far as the cinematography goes...could this be achievable in ROTJ:R? I sure hope so..."
Don't we all wish it were achievable. But not the level of enhancement Angel has made. Those changes would have to be made to every single frame, match-moved, etc. It's incredibly difficult, and virtually impossible to get right. The lighting, contrast and colour of a shot can be tinkered with and greatly improved much more easily but when it comes to specific elements being changed frame by frame, it's nigh impossible. I think Angel's mock-ups are really great, some of the changes are beautiful, but they stand as more as a "Look what could've been" rather than what can be done.
