 I don't think that will work, on psychoacoustic grounds.
Because, an AGC works by trying to produce an equal average power
output - which works for uniform program material, but any synth noodler 
knows that
some waveforms are 'percieved' louder than others, even at equal power, 
dependign on
harmonic mix.

I'd advise making somew actual observations - listening and comparing 
various
mixes. I don't think this can be solved from a theoretical viewpoint.

Fortunately, with signal generating software, it should be possible to do 
this.
