Sorry, I'm totally not following you. Can you explain how the setup pictured in the OP is different from a single sidepull in the sense that, even if the calipers are unequally spaced from the rim, upon brake application, one by one, they first contact the rim, before any appreciable braking force develops? Assuming return springs and pivot bolt friction is the same on both sets of brakes, the braking force on each pad will also be approximately the same.
