You have a misunderstanding of fluid systems. The force/pressure on you MC is exactly the same as it was before you upgraded your brakes. The pressure in the lines is entirely dependant on the force you put on the pedal with your foot.

When you upgrade to a larger caliper with a larger piston area you increase the output force at the caliper end but from the same line pressure.

There is obviously some science to be done to match MC's to calipers but your braking system is no more dangerous than it was before.
