I don't think that's possible.  Faces are referenced thru
symbols. Ie. the way it is implemented, faces are not first class
objects, they're attributes of symbols.  Symbols aren't specific to a
buffer.

The best you could do is to create new faces for each buffer, copying
the faces you want onto new gensym'ed symbols and refering them thru
buffer-local  variables.  Of course, since normal font-locking code
refers the faces "literally" thru the symbols they use, you'd have to
patch them or program your own font-locking.
