Hi Eric,

I don't know how to change `font-lock-comment-face' on a per-buffer  
level.

What you can do though (I think) is use the function `font-lock-add- 
keywords'
to add your own regular expression for matching comments and specify
an arbitrary font for this match.  For example (untested):

  (font-lock-add-keywords 'org-mode
   '(("^[ \t]*#.*" 0 my-org-comment-face prepend)))
