Very doable, I have one laced up on a 700c Mavic Open Pro rim, and am running 23mm tires. I did have to order spokes to fit. One thing that does matter (not in rim size but in exchangeability between frames) is if it is a hub that uses "Rohloff OEM" dropouts or is it one that uses the torsion bar. They are the two ways Rohloff keeps the hub from spinning, and the torsion bar can be used with any dropout and the "OEM" hubs, not using the bar, must be mounted to a Rohloff specific dropout.


Rohloff w/torsion bar in vertical dropouts and eternal shifter.
