I'm happy to share. It'll take me a couple days to simplify the files. Right now they're all layered Photoshop files. I'll upload the whole package by the end of the weekend..
One big caveat: the slipcases and bluray art are designed to use Criterion cases. Unfortunately, it'd take quite a bit of work to adapt for the regular bluray case sizes, particularly on the slipcases which proved to be quite tricky to get right. You can buy blank Criterions on their site.
