Brake Cooling Project Update #3

The latest update has me going crazy....  I've had a few ideas; pretty much everything has failed. The failing reason has been constant; there's just not enough room in the front of the car to run adequate ducting on the OEM IX bumper. My larger upgraded FMIC blocks the middle, the piping blocks the little 'faux' holes. 
I have an old pic from I think an 03 Evo where they ran NACA ducts in the front bumper of the car for what I assume is brake cooling ducts. I'm not sure if the oil cooler is in the same spot, but I know this car did NOT have the ACD pump on the driver's side to deal with.  This post details my attempt to either run from the headlight holes - custom covers would be needed to block out the rest of the headlight gaps obviously, or from the top corner of the bumper. 

The problem with that idea on my 06 Evo is that the ACD pump clogs up the right side. Besides the duct routing issue, I think there's room to put the inlet duct in the mesh actually and not have to cut into the bumper at all. The ACD pump is an issue either way, but I think there's room to route behind and around it. You just get a quick downward bend unfortunately. (see 1st pic).

On the passenger side, I really don't see a good spot to jam the duct in really. The front bumper crash beam is a bit in the way, but you can probably still find room and/or remove it. You'd probably have to cut into or push the top rear corner of the oil cooler ducting a bit to find room to route the ducting. Or another option (like I show it below) is behind the oil cooler; this probably isn't as good an option but was easier to route quickly for a picture. Again, this side is doable I think but you get another quick downward bend unfortunately. (see 2nd pic).
