I don't understand. The issue with the cost model should only be that getIntrinsicInstrCost may not have implemented the cost for all vp intrinsics. Alternatively, you could choose one of the vp intrinsics for which getIntrinsicInstrCost has already been implemented as a demo. 
Then we can discuss what to do about invalid costs.
