Fenders which fit above rim brakes?
You could do this with off-the-shelf reacharound brackets. You can also make them out of leftover rack upper stays or other flat strip metal stock.
The idea with them is you take a fender set and cut them where the fork crown and seatstay bridge are, so the fenders don't have to go under them or the brakes. Then you drill holes in the cut off pieces and bolt the brackets on.
