The time was ripe for ANH thanks to Harmy's Respecialized edition. I'm waiting for more sources. I'm thinking Kk650's ESB would do well as a base, with Adywan's version of the Emperor scene. (Technically this deviates from sticking with official releases. However, it does hybridize the original and '04 versions of the scene. It gets an exception.) And Harmy's ROTJ 2.0 is a must.

ESB won't vary much from kk650's, and ROTJ will be largely the original version. I may not release them if they end up being very similar to one particular version. But that won't be a question until the sources are released.
