We never had such a fun name for them, but here in Eugene we did a very similar thing. We used rack mounting brackets. (the pictures in the link are very good) Sometimes just cutting the fender and zip-tying the pieces in place. Also, PB's Freddy Fenders use zip-ties to mount a bracket to the chain stays. Looks pretty effective. I'm sure you'll be successful.
