This second order microphone will not be expensive. It is only eight

output nine channels after processing.
You can imagine a tetrahedron surrounded (on the horizontal plane) by
four capsules at 0, 90,180 and 270 degrees. That is basically the
array design.
Very nice - gives easily 2nd order in the plane.
It should be possible to apply some (moderate) upsampling strategies
to receive full 2nd order... Angelo Farina seems to be being able to
think above 4 harmonics and so you two will (probably) succeed. O:-)
Just: "... to be able to..." Sorry!
