The stopping benefit from larger rotors is not the sweep/contact surface (although it adds to the joy of course), but the longer imaginary lever from the center of the hub, at which the rotor is grabbed by the caliper.How big is an upgraded rotor? Also, take into consideration that size of rotor includes the hub. So the sweep surface might still be small. My Sequoia has a smaller sweep surface than both BMW and Tiguan, and those two cars weigh 3,600lbs, while Sequoia weighs 5,934lbs!
Your original pads and calipers will have a stopping power that will increase the larger rotors you mount them on, all other things being equal (same pads = same contact area)
See how those puny two little pieces of rubber can throw you across the handlebar on a road bicycle with 26 inch wheels, whereas larger "grabbers" do close to nothing or very little on a kids' bike.
