Many folks have done it . . . but the question is when this "additional
stopping power" is going to come in handy.
Since a huge proportion of the braking is done by the front wheels (front
engined car + weight transfer under braking), the first objective is to keep
the rear brakes from locking up under heavy braking. If you can lock up the
rear drum brakes now, then the last thing you need is more efficient disk
brakes in the rear.
One of the main advantages of disk brakes is that they cool better and
resist fade under repeated applications. For normal highway driving, or even
autocrossing, additional brake cooling may not be of particular help. For an
all-out road racer, on the other hand, disks on all four wheels may be a
considerable advantage. Jaguar disks on the front and the TR disks moved to
the rear is one possibility.
Just MHO, of course.
