Wally, your upgrades show an impressive amount of engineering and craftsmanship with a successful outcome. Rear disks require the additional fluid that your system provides. I have stock rear drums but was able to improve braking by replacing the vacuum booster with a Hydro boost system. This upgrade from stock increased the fluid pressure and stopping ability fairly significantly. Fortunately, this fits under the hood with space to spare.
There isn't adequate space under the hood for larger capacity master cylinders needed by rear disks. To overcome the space problem, I understand another solution is in the works. It is an adaption of the bell crank system to actuate a larger capacity master cylinder. Like your solution, it will provide more needed fluid to rear disks. Similar to what Jim Hupy described, the bell crank connects to a front frame mounted large capacity master cylinder. All this to help bring our seventies technology to the two thousand twenties and fit it under our hoods.
