Fly the whole living, healthy, poor person to the rich country and replace the person who needs new organs. Education costs are probably less than the medical costs, but probably it’s wise to also select for more intelligent people from the poor country. With an N-year pipeline of such replacements there’s little to no latency. This doesn’t even require a poor country at all; just educate suitable replacements from the rich country and keep them healthy.
