Would you agree to have yourself cloned for the purpose of replacing your organs later in life?

imagine if you were 50 years old and with a severe heart condition. the prognosis is bad, or would be if not for the fortunate coincidence that, 30 years prior, you agreed to have yourself cloned. what would've been your sure death is now nothing more than an uncomfortable hospital visit, and 2 weeks later you're out with a brand new heart. there would be none of the tissue rejection issues ociated with today's transplants, and you could reasonably expect another 20-30 years added to your lifespan. would you agree to such a deal? why or why not? the "clone" would not be a complete clone in the sense that only viable and useful organs necessary for YOUR health would be allowed to develop
