It is possible to mount a regular wedge (well, a Topeak one at least) on a Brooks - mines a Professional. Simply unscrew the clip from the inside of the pack, put it back on 180 degress from where it was, and attatch the other part to the rails at the flat part before it kicks upwards (immediately behind the seatpost clamp). It's a bit awkward to get on and off, but it works fine.
