That would be too bad, but we actually did what you're talking about. I did the torrent updates in 2012 and 2014, and we upgraded the encodings/bitrates of more than 500 ReMixes. Some of the stuff you linked to were artists creating new or expanded versions of their tracks, which we wouldn't replace the posted ReMixes with, but perhaps djp would be open to hosting alternate versions in a non-featured way. It's never a bad time to reach out to artists again, but I'll clarify that I already did do this work before from 2009-2014, through a mass email to all ReMixers, and a forum thread where some fans also provided better encodings that they'd saved.
Excellent choice, all yours!
Now that I've seen a few drafts, it's worth throwing out a reminder to everyone who hasn't sent anything in get: please reference the sample WWE theme songs for style and structure! In particular, the intros and build-ups are always short when there's any at all. Most are just 10 seconds max before getting into the meat of it, but there's also a common format of 10 seconds intro, 20 seconds build-up. 30 seconds before the main melody starts is definitely the outside limit.
