If you use the larger diameter brake cylinders, for the same amount of brake pedal pressure, greater pressure will be exerted to your front brakes and thus they will brake harder. You would not want to do this, especially not if you use softer brake linings also. You risk your front brakes locking up when braking, which leads to loss of control.
Go by the specs in the book, I’d say:
