The bigger cylinder will require more fluid volume to make it move, causing a low brake pedal, and once it gets applied, there will be a hard pull toward the cylinder with the bigger diameter due to more force being applied to the brake shoes by the bigger diameter cylinder. DO NOT DRIVE until you get the right cylinder installed.
