Having just watched the Snyder Cut hot on the heels of re-watching the Whedon one… I really don’t think there would be any benefit for adding anything from the latter into the former.

Two main reasons for this: 1. A SURPRISING amount of Snyder’s footage is still in Whedon’s version (just absolutely butchered all to hell in every aspect imaginable) and 2. The stuff that is exclusive to Whedon’s cut (certain different character interactions) are really just supplants for much better scenes and dialogue in Snyder’s version.

Honestly, the best way to approach a fan edit of this is to maybe trim down it’s length a little (a lot of scenes go on far longer than they probably should) and make it 16:9 tilt and scan. But, I’m absolutely fine with just leaving Whedon’s version in the dust where it belongs.
