Using my car as a reference here:
In my opinion, the LED slots are too small and irregularly shaped to efficiently provide sufficient cooling. They are also too far outboard and relatively high on the bumper. You'd have to come up with an interesting bracket to mount your hoses, and then route your hoses back in towards the center of the car only to bring them back out to mate up to your brake mount.
You'd be better off using the "fang" area to mount a vent to attach a hose. The routing would be much simpler as would the mounting system.
