Freehub body swap on HED Stinger wheels?

Is it possible to change out the freehub bodies on HED stinger wheels?  I have a chance to purchase some new wheels, but the rear has a campy freehub, I'm using shimano drivetrain.  Will I be able to swap out the freehubs?  If so, where can I get information on this.  I'll have my LBS do the swap, but want to know how much to expect to pay.  Thanks

 This is for either 2007 or 2008 wheels....not the 2009 wheels (not sure if its 2007 or 2008)
