Yes, although I assume others somewhere must be thinking similarly. It seems self evident to me.
I post this idea on HN every now and then when I see the subjects of cancer, aging, or death come up.

Incredibly difficult. This is an Apollo project.
You'd need egg donors, good embryo yields, a protocol that sustains life throughout development, womb surrogates, decephalization that doesn't kill, life support systems at every stage, birthing, machines to keep them alive after birth, ...
Once you've worked out the kinks though, this thing prints money. But that's not what's exciting to me - this gets us one step closer to ending death.
I don't think we've taken a single step in that direction yet, so it'd be nice to finally get started.
