While you could probably provide for this type of buyout, it sounds like a recipe for disaster. Trying to project five years into the future of how much work will be performed based on someone who no longer owns the business, invites litigation.
A cleaner way would be to have a fixed amount for the buyout provision. Then enter into a different contract for five years for future work.
