Piston count as well as diameter play a big role in braking power as well! There is math behind how much proportion will go to which caliper which also depends on size of MC or the piston/bore within (in addition to the two prior mentioned conditions), if I remember correctly
Unless its a full bore GT car or prototype endurance car, its very rare to see front and rear having the same exact setup be it street or race car (and the biggest reasoning to have similar setups back/front is for adjustable proportioning and balancing the car out for long distance races as fuel is burnt, tires used up, rubber build up, etc)
Also, this is VERY important to mention. Race cars go with bigger brakes not only for the increase in torque, but for the simple aspect of longevity (think controlling heat, heat transfer and heat dissipation due to increased surface area).
Now, here is where you will run into an issue Trey. Stock rears with proper rotors and stock calipers will or will not be within their temperature operating range on the street. By going with a bigger rear setup, you are making it even WORSE as you are going in to opposite direction away from the operating temperature range of the brakes!!
Simply put. TERRIBLE IDEA ALL THE WAY AROUND!!
By that is my personal opinion and you do not have to take anything I say if you do not like.................
