yes Matts uses Vbap between two arrays for height - but only works on

unless i'm misunderstanding something, that remark doesn't make sense.
vbap is amplitude panning between n-tuplets of speakers (usually for
1<=n<=3, unless you add "spread"). between two layers of wfs, all you
need is simple constant power panning, like in a stereo panpot.
the downside is that height localisation in such systems is just as bad
as with auro-3d, and i find dual-layer wfs terribly wasteful.
all the top layer can do for you is add "spaciousness", unless you are
really interested in precise localisation on two strata but nowhere in
between.
but if it's only about spaciousness, you can add as few as four height
speakers to a horizontal wfs and get great results already - IOSONO have
demonstrated this very impressively at ICSA 2011.
so by all means concentrate your speakers on the horizontal plane, and
then since you have so many, use maybe 16 or 32 for an additional HOA 3D
setup (or just feed them discrete ambience).
