The problem is that Campagnolo changed its spline pattern when it went from 8 speed to 9,10,11,12 speed. An 8 speed Campagnolo cassette(if you can find one) probably won't fit on that pictured 9 speed wheel. Shimano 8 speed cassettes are about 2 mm narrower than 8 speed Campagnolo cassettes, so shifting will be off a bit at the extreme high and low ends of the cassette.
