Sorry there man but if you want to use PureBDcraft (a.k.a Sphax pack) then use PureBDcraft. It would be copyright infringement for anyone to take Sphax's hard work and edit it then redistribute it to someone else.
a.k.a Sphax holds the copyright to PureBDcraft, only he can distribute it. It's against the forum rules and against their own TOS to share their work, even with edits from any other source then their own site. http://bdcraft.net/sphax-purebdcraft-texturepack
The unlawful use, redistribution and/or exploitation of intellectual property that is protected by copyright, patent or trademark.
The four basic elements that can establish copyright infringement:
All of the work is exactly copied or reproduced
Part of the work is copied or reproduced
Reworking (or paraphrasing)
Copying the TOTAL concept, feel or essence of a work
Infringement can be punished by law including but not limited to recovery of monetary losses, punitive damages and/or misdemeanor or criminal prosecution.
So sorry, no. Anyone who does do this, would end up in deep trouble, and Sphax is on these forums, I don't think you want someone as big as him on your tail for stealing his work.
