Anyone ever eliminate the prop valve?

I've had trouble for months trying to get my brakes right, and I'm considering eliminating the brake combination valve. I'm thinking of plumbing the master to the wheels directly by running the front M/C reservior to a TEE, which will run to each front wheel. For the rear, I might run a line to an adjustable proportioning valve, which will then just run to the axle and split from there.
Has anyone out there made this change to their cars?

That's exactly what I am running on my manual 4 wheel disk brake car.
It's what the tech guy recommended from master power brakes.
