The cable pull and cog spacing are different on Campy than they are on a Shimano compatible rear wheel, and a Campy cassette will not fit on a Shimano splined hub.

To the OP: If there is nothing wrong with your hubs, find a decent wheel builder and just have new rims lace to your existing hubs with new spokes and spoke nipples. A quality built set of hand built wheels will last you a long time.
