I would think they would be interchangable if the bikes are both running 7/8 bars. I like the idea of the mirror clamp a lot. Here is a picture of the VFR 14mm brake and clutch masters, and a picture of the brake mounted using a bar end mirror set up.
Interesting work, looking forward to hearing how it works. I have been using the master from a Honda VF1000, price was right on ebay at about 35 bucks.
