Hi Steve,
An interesting proposal. You'll excuse perhaps my misunderstanding here,
but my understanding was that ambisonics A format consists of a omni plus
x,y,z to give 4 signals that are then converted to b format . I built my
own ambisonics mic and decoder once a long time ago so perhaps things have
changed, I think I put Left + & - right = x Front + & - Back = y Top + & -
bottom = z All summed * 0.257 = w into my decoder.  . Anyway I digress -
this basically will give you a sounds position in 3D space , or at least on
the surface of a sphere proximity not being so well recreated. So if you
had say, 8 ambisonics mics pointed in 8 different directions ,in order to
record that small 8th of  a sphere (or in this case cube) in the direction
they are pointed in (which is what the ORTF does)  - how would this work if
the decoder if a format gives spherical coordinates rather than an 8th of a
sphere/cube (hope this makes sense), and with the capsules pointing in all
directions... ?
cheers
Gus
