The V.O rims are very tall and wide, great for building touring rims, but not very vintage looking, at least too me. I have yet to find a new polished rim that I like. I recently built a set of wheels using High Flange Campy hubs, Mavic Open Pro Rims and DT Swiss Competition spokes.
I took off the Mavic Open Pro Sticker ( very large non vintage looking) cut the "Mavic" out, and placed over the seam. I think they look the vintage part.
Even more than this, I'd suggest test fitting a 622 wheel with the original Campy brakes and make sure they won't work - there's a good chance that they will. I replaced my Trek 610's original 27" wheels with 700, and until I had a new high-rake fork made, have been able to use the original Shimano sidepulls. There's no "given" that says your original brakes cannot work.
You can also estimate the brake reach requirement by measuring. Measure the distances from the center of your rear wheel axle to the center of the brake bridge hole and from the center of the front wheel axle to the center of the fork crown hole. These should be in millimeters or 16ths of an inch, and done carefully. Then measure the distance from the center of the wheel axle to the center of the brake track (the rim radius). Subtract the rim radius from each of the first two measurements. The results are the estimated necessary brake reach for the front and rear wheels, on your bike. These numbers will be good for the 27 inch or 630 rims. Add 4 millimeters to the reach for each wheel to get the necessary brake reach for 700c wheels. Compare that to the reach of your brakes to see if they should be tried out before spending $$.
