Think about it this way: your brakes are activated by moving a certain volume of fluid at a certain pressure over a certain distance. Since the distance is fixed, there"s nothing you can do about that factor. So if you go to a smaller diameter master cylinder, you have to have a longer stroke of the master cylinder piston, or you will lose volume of fluid moved per stroke of the pedal. And since you can"t change the length of the pedal stroke [assuming you use the stock pedal], your brakes simply won"t function as well...if they function at all..using a master cylinder with a smaller-diameter piston. And just adding a booster won"t add to the volume of fluid moved. If you use a master cylinder with a larger piston, you"ll move more brake fluid volume per pedal stroke...meaning it"ll take less pedal for the same braking action, but there also comes a point of diminishing returns...that is, too much fluid moved in too short of a pedal stroke will make it more difficult to slow down without locking the brakes...making any "improvement" more of a PITA than it"s worth.
