I think the Campy crank has one bolt not on the 110 mm circle, so you might have to modify the Campy chain rings if you want them to fit on a normal crank with all the bolts on the 110 mm circle.

Here's one reference that claims the Campy cranks models with the hidden 5th bolt have it on a 112 mm circle!

ONLY THE CARBON CAMPAGNOLO COMPACT CRANKSETS HAVE THE ODD 110/112 MM
BCD CHAINRINGS. The aluminum Centaur and Veloce and Mirage, yes all
three groups have a 110mm bcd crankset, compact cranksets all use
stanard off the shelf 110 mm bcd chainrings. The ones that use the odd
110/112 mm bcd are the ones with the hidden spider arm on the backside
of the crank arm. All of the standard looking 5 arm spider cranksets
use 110mm bcd chainrings.
Nothing that 5 minutes with a $20 kmart dremel won't fix. At least
they made it 112 bcd rather than 105 or something that a dremel
couldn't fix. I guess they were thinking of the budget racer who buys
$10 sugino rings and has the $20 kmart dremel in his garage.
