Well....  You may just find out that the overdriven VCA gives the Etherwave 
part of its basic sound, which is more grungy and fatter than a pure sinewave 
theremin.  They were trying to emulate the tonality of the old RCA tube 
circuits, and the overdriven VCA might be part of that.  You might need to 
leave that VCA alone, and build an additional VCA stage for your new 
waveforms (an external audio input could also be a useful feature, especially 
if the theremin has the CV output mod).

Let us know how your mod turns out!
