Maybe. I looked into this, thinking it would be the perfect solution to making the lht feel faster. I wanted to raise the bb and a few other things. I did some of the measurements and it doesn't look like its possible with standard canti brakes. You'd have to go with paul v-brakes, and slide the pads well up the brake arms. I'd imagine this would change the pull ratio and the braking power for the worse. I plan on trying it in a few days with an actual wheel, now that my bike shop actually has some 650b's in. I can let you know, if you'd like. Even if it did work, your tire selection would narrow further - exacerbating one of my points of contention. And, paul brakes are pretty pricey.
