I think ditching the 'retro classic etc' labels is probably wise. There were always only minor differences between two of them, and not much enthusiasm behind the Technicolor. If people care all that much about such differences, they can achieve a similar result by adjusting their displays.
The way you were discussing it, it would have been 6x ANH and ESB uploads, and 12x RoTJ. That would have been a ton of poorly seeded torrents before too long.
