There is always the option of doing up some pathfinder classes as associations.

Unique ones would be....

gunslinger

Vitalist

Tactician

I for one would LOVE to see an association built around using Vitalist or Tactician.

But if We are keeping it 3.5...Hmm..

There is a Lycanthorpe, but nothing I remember seeing more of an anthromorphic animal....

Otherwise I think everything is pretty much covered, cept for really unique Homebrew classes...Maybe Tome of Radiance? or Spellshaping?
