Maybe stupid but I was thinking of going exactly the opposite way, 2 small K&N one directly on each turbo, eliminate entirely the present convoluted intake tract. So many folks with big turbos have NO intake tract at all, just a tiny K&N stuck right on the turbo itself and they make huge power.

You deal with intake temps on a turbo with FMIC and maybe meth, not so much a CAI. You could easily redirect some cooler air back down there from the front, even exiting under the car.
Also would need to vent diverters to atmosphere, but that is easy just slap on couple of tiny K&N's right onto the diverter exit.
