Sure, I think you can put rim brakes on a bike configured for disc brakes. Just mount the calipers, I guess. Assuming there is a mounting hole. But the other way won't work. My frame is setup for rim brakes, thus the narrower spacing between the dropouts. I can't just take off the disc and put the wheel in; won't fit. Too wide.
Not talking about the actual rim, it's the hub that is the problem.
Somewhere here on BF I started a thread asking that question and I got many helpful answers.
