But I see a more serious problem. Shotgun mics work by integrating pressure over their lenght. That means that the effective radius (the one that determines phase/time differences between capsule signals) will be around half the physical one. And that is rather large, it means that any linear A/B matrixing will start to break down around 2 kHz.
Also, shotguns by design have lots of frequency dependent nulls in their directional pattern, and the pattern itself is likely a mixture of lots of spherical harmonics of varying, high order, probably with directional aliasing already folded in for good measure. I would imagine it to be rather difficult to invert the resulting system into something well behaved.
Anyway, how to calibrate such a thing and get the best out of it is difficult to say without first studying a set of measurements.
Agreed.
