Nope :(
I find that if you use L brackets that the part that goes into the fender you have a thick nut that is either going to go under the fender and interfere with the tyre or go between the bracket and the brake. This can be avoided by using pop-rivets on the fender L bracket attachment and using a Sheldon nut on the backside of the brake.

Craig Gaulzetti showed me a trick where you swap the front and rear calipers and then using rim-rattlers space out the rear brake that raises the fender mount.
