Has anyone retrofit the 135i Air ducts w/128i Performance Bumper?

I was thinking of doing the same thing - after staring at the realoem diagrams and the install .pdf for the Performance Bumper I don't see a reason it wouldn't work, but it'd be a nice reassurance to hear someone else has done it before dropping the money on the new bumper and fender liners.
