I share your sentiment, Steve, but it's sort of like "trying to make a silk purse out of sow's ear." As you know, the caliper is 2nd gen. While it does have two live pistons, it's pads are too large in diameter such that the travel speed of the disk past the pad's inside edge is much slower than it is at the pad's outside edge. That speed differential translates into excess heat differential between the disk at the inside edge and at the outside edge. That's why some discs - under heavy sustained braking - crack, especially after they've been drilled. That's why the 3rd gen calipers/pads are smaller in diameter and, to retain surface area, offer two or even three pads in series.
It's a good caliper, handsome too, not much weight to be saved at the caps anyway. How about reduce weight instead by way of a light Borranni type valanced rim?
