I do it regularly to set up super commuters. Allows me all weather tires, including very large snow tires without taking off the fenders. I run Mafac Racer brakes in front which will reach on almost any bike and still stop with power. In back I use whatever reaches, power not being very important. (You can find Mafac Racers in many shops used brake box. Usually ~$5-10. Get ones without too much play in the pivots. (They will work fin with a LOT of play, so a little means many years left.

Now you can get Paul's brakes with the same geometry, far more class ans whiz factor and lighten up your wallet a lot. (He has the wisdom to copy the best stopping brake ever made and has the engineering knowledge to design out the "funk" that was/is so integral to the Mafacs. But new modern pads on the Mafacs also remove a lot of that funk.)
