If the disc brakes are mounted on the chainstay rather than the seatstay, which looks like the case in your photo, the non-disc version might clear everything with no problem, but it might have the same overall spacing anyway. You could probably just pull them apart ("cold set them") enough to fit over the mounts, if it doesn't start to distort the rack too much?
