Why? OK...consider this one: take your quadrature outs and mix the 0 and 90 degree together, then do the same for the 180 and 270 degree EGs. Send the resultant mixed outputs to a pair of, oh...let's say Intellijel Polarises...control inputs.
When you say 'mix the resultant outputs' of Quadrature, do you mean use something like Links to do that 'mixing'?...

That's one possibility. Better still would be to use a variable-level mixer instead of Links so that you can fine-tune the feel. Or if you're working with a quad VCA (Veils, et al), just send each EG output to a separate VCA control input but only have a single audio input to the four VCAs. Futz around properly, and that'll get you into a whole weird territory that's normally occupied by the ARP 2500's Mixsequencer.
Loads of abuse potential in/with quadrature!
