No, unfortunately if Campagnolo had modified the profile a bit they would have been terrific pedals.
The inboard steel bearing cone is pressed on to the shaft, the added dimension drove the need to go with a smaller ball bearing size to use the same body. They could have used the same parts as the other pedals outboard...
In my opinion if they had done away with the reduced diameter between the pedal body and the wrench flats the pedal would have been a winner. An almost direct material substitution was not the way to do it. Ti does not have the same stiffness of steel for the same cross-section. This foretold the problem Campagnolo would find themselves in a decade later, poor engineering design choices.
