Even with long reach caliper brakes, the distance is too great.
There are such things as brake "extenders" where a bracket is placed on the existing brake mount on the frame, and then the mount point is effectively lowered, but it is not at all a safe application for cross IMO.
Ahem. Google "650B conversion" and you will see that plenty of people have done successful 700C to 650B conversions. There is actually a pretty decent selection of tires and long-reach calipers out there. It's not a panacea and won't work for every bike out there, but it can be a viable option for people wanting to run fatter tires on their road bike.
