the way i look at it is ; does one magura caliper work better than two? the same idea, 2 calipers with a cross over of some sort. more fluid in the line. does each magura caliper get less fluid because there are 2 of them? no. that would make the brake feel very spongy or not work at all. IMO, yes, you would get a significant advantage because of the greater surface area and less heat (the concept the gatling gun uses, more barrels less heat on each) on each caliper. id love to see this tried and tested.
