Sorry Rick, I don't think one can selectively apply the laws of physics as they choose.
Although the effects of comb filtering can be more obvious when both mics are in the same sound field, comb filtering, per se, does not demand that mics are close together. Maybe I'm missing something.

I'm curious as to how the double EQ approach sounds when the resulting stereo mix is folded down to mono.
