Oh, God, no!

You realize the rear brakes in a disc/drum combination need a whole lot
less line pressure than the fronts? Otherwise you're flopping around with
your rear wheels locked up all the time.

If you plumb dual-diagonal (and I'd note that some Euro cars do this, as
well as Ford Tauruses - pre-ABS Volvos plumbed a 'dual triangle' with each
piston of their dual-piston front calipers on a separate circuit to ensure
both front brakes always had at least SOME actuation) you have to have two
proportioning valves in the rear brake circuits.
