Guys, lets do some basic math. The mechanical advantage you have when pushing on the brakes is basicly the volume of the area behind the pistons in your calipers divided by the volume of the fluid you displace from the master cylinder. Going to a larger diameter caliper piston, you indeed gain brake power at the expense of pedal travel. Now if you enlarge them both, the master cylinder and the caliper piston diameter, you may very well end up right where you started only without any money left.
