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.

You would end up right where you started in terms of pedal travel, but the larger volume of fluid pushed through the larger master cylinder would mean that you have a greater potential for stopping power. More volume in the caliper with the same at the master cylinder = less pressure. Upgrade both retains the stock pedal travel with more stopping power.

My thought, but then again I haven't done the swap yet. Experience only from what I've read.
