First of all, Pressure is defined as Force per unit Area. Pressure = Force / Area.
But regardless of that definition, the hydraulic connected to the brake-pad applies a constant Normal force, not a constant Pressure.

So the relevant equation is F = u * N. Note that Area has NO RELEVANCE on braking force.

However, P = N / A (where N is constant). So increasing the Area serves to reduce the pressure applied to the disc. Therefore there is less heat dissipation per unit Area - the disc runs cooler. Now this can be a second-order effect on braking efficiency - not sure whether hot vs cool discs are more/less effective.
it all depends on the material. cast iron rotors are really good at dissipating heat, stainless ones have a much higher thermal impedance. GP rotors are carbon ceramic, which need to be super hot to get full grip, so they have an even higher thermal impedance. the pads need to be suited to the rotor material and operating temperature.

The rotors look pretty sweet. I don't think I'd be too quick to do the fronts, but cutting away the rear like that is pretty common practice.
For sure the pad wear on the front is going to be pretty rapid due to the increased surface of edges. That's the idea behind wave rotors, but even the big names in brake disk manufacturing have avoided cutting away the interior of the front disks like that.

waste of money from my point of view.... If you understand physics that well you should be helping Triumph Design them... There is a reason why Rotors are the way they are. Pedal rotors are much different than taking your stock rotor and cutting it.
