If "3 dimensional" is high on your agenda, then IMHO you're throwing far too many mics at this. You could end up with a pea soup or pasteboard result, where there's little element of integrity, seamlessness or sheer "rightness" to the imaging.
Keep it simple and don't overthink it. Lose those elevated AT's. Concentrate on first miking the (sensibly arranged) ensemble as a whole with a single Schoeps pair, say, an omni AB (most likely) or cardioid ORTF, from a distance of ca. 2-3m. That may be all you need. Listen, adjust, listen... till you've optimized that as far as you can, before reaching for those additional mics.
