This is almost a trick question, and you did not even realize you were being tricky.
If you use a chevy rotor for the rear disc brake conversion, a 15" wheel can and will fit, and does not require the same backspacing as the same 15" wheel for the front.
The solution here is simply to run a 15 inch wheel with 3.25 inches or less backspacing, and regardless of bracket design, the wheels will fit both the front and rear, with very little to no caliper grinding.
I have been running 15" wheels (on 1 ton axles) with 3" backspacing for years with zero grinding on the caliper(s).
