FYI, it's possible to run a nearly ideal M/S setup with Schoeps actives + MK caps and a Vark bar. Two reasons it's not ideal: <a> the front of the Mid cap aligns ~5mm forward of the exact center of the Side cap (the actual distance is probably less, since the Mid cap's diaphragm is set back a bit from the front grill) , and <b> the bend radius in the active cable is a little tighter than I'd like, but it's not too bad (see pic 3). I may pick up another Vark bar extender (the piece in the first pic that's screwed onto the back of the cylindrical bar running through the shockmount) to run the caps a bit farther off the drilled-hole base to reduce the bend radius. At any rate, close enough for me, for now. Pics attached.
Edit to add...
The WMS windscreen fits the caps in this arrangement.

Another edit to add:
To reduce the rearward footprint (the Vark bar rod sticking out the back of the shockmount), simply remove the Vark bar rod and replace it with just the spacer. The spacer sticks out enough to slot into the shockmount and hold securely, but it doesn't protrude out the back like the full rod.
