The most important thing in all of this is the proportioning valve. The risidual valve has to be there for the drums (front or rear) and it cannot be there for discs. The only real need for the larger volume of a disc brake master cylinder is for the volume need as the pads wear down. The rear brakes are adjusted by the screw adjusters at the bottom and the fluid requirement doesn't change as the shoes wear. If you keep an eye on the fluid level, you will be ok.
The amount of fluid need during the actual stop is not that much different.
An adjustable prop. valve is a good idea though.
The biggest benefit of discs on the front is in the "automatic fluid adjustment" that keeps the brakes working more evenly. You don't get a pull from one side being out of adjustment.
