>Create a genetic clone of yourself like what has been done with dolly the sheep
>During the pregnancy, you inhibit the HOX-genes that are responsible for differentiating a head segment
>Woman gives birth to a headless genetic clone of yourself
>Supply it with hormones and nutrients via IV so that it develops properly
And voila you have patient matched backup organs for when they are needed (you could also get a megacock if you blast the backup body with the right hormones during puberty). It's not unethical since you aren't causing a sentient being any suffering and it would create a brand new sector in biotech causing new jobs and economic opportunity.
