Hmmm, never tried that, nor even heard of it - at least that I can recall -
the closest I've come to that is when I was messing with some SM-81's (and
that mic's got a pretty wide pattern, IIRC) some time ago & ended up with a
similar arrangement (but I don't think it was nearly a foot - more like
maybe 8 inches apart, max; which seemed to work pretty well for the room I
was in at the time - was just trying to find the positioning that rocked &
that seemed to do it). Got a good hyper that you can recommend for such
tasks?

I've used AKG Blueline hypers, AKG C480B hypers and latterly Schoeps
CMC641 supercardioids.

What does it do? Meaning what kind of characteristics is it supposed to
impart?

For my ears it gives a more accurate stereo location. You have to pull a
little further back than with the ORTF set as the included angle is not as
wide. And you get a better rendering of the room. The NOS setup was
proposed by the Netherlands public broadcasting chain. Try it sometime,
but in a good room.
