   I believe that this is very much what the later Yamaha FM synths did.  
Correct me if I'm wrong, but the DX-7 was sine only, right?  But later 
ones like my DX-11 allow for different kinds of waves (saw, tri, etc.) 
but was reduced to 4-Op.  I think there were some 6-Op's available 
(DX-21? or DX-5?).
   It is also possible to do additive with different waveforms on a PPG 
Waveterm as well, but the programming is rather clunky!
   I hope that I'm on key with this discussion!  ;)
