The easy Forth solution would be a stack-based thread implementation.
However, Forth is very flexible, so perhaps CPS could be supported.  I
would think that building it from scratch would be biased toward a 
Scheme implementation as CL is rather daunting.  

Hey, CMU-CL experts, how hard would it be to get CMU-CL to generate 
bytecodes, or Forth?  Should be easy, unless the backend is really
biased toward a register based machine implementation.

Good luck.  I've never seen or heard of one.  Like I alluded to earlier,
a Forth programmer good enough to write lisp-over-forth would say "why 
should I?  Forth is perfect!"  On several occasions I started a Scheme in
Forth, but never got very far.
