Probably not.  There has not been any request (that I know of) for this 
before, and it is a bit of work to do.  Each Emacs window in the same frame 
shares the underlying X window.  Setting the background on a part of an X 
window means drawing it manually.  It can be done, but I think it is a big 
change.  Now, if each Emacs window would have its own X window, then it would 
be easy.
