The Op is a silly question. Medical ethics questions arising from emerging scientific and medical breakthroughs are going to dazzle everyone, and not always in a good way.
In my lifetime, an artificial heart, a pig heart and the heart of another human has been used to extend the life of a person with heart disease. At each advancement, the public thought the implications were sinister and you can still watch recently-made horror movies where a person is killed so their organs can be harvested. Probably 75% of the non-medical public is afraid to consent to donate their organs out of fear they'll be killed by doctors so someone else can live.
When we know what may be possible and have a chance to observe the unintended consequences, then we can discuss human cloning. Daisy the sheep seemed to live a healthy life, but how would we know whether a sheep was mentally ill?
Whatever we do, I imagine we can count on the Roman Catholic Church to condemn it and possibly, that will carry weight with a Justice or two (Scalia and Thomas, if they're still on the bench) but this will never, just as it has never, serve as more than a nuisance.
Progress will progress.
