I think the key word in the whole theory is possible. To date it hasn't been done, but that hardly makes it not possible. Isn't possibility the whole driving force behind scientific research. Not discovering again what has been done but reaching out into the realm of "fiction", sailing around the world, flying to the moon, cloning sheep.
It would be completely a scientific process to be sure. ( I will also give you that I was taught at one of the most liberal colleges around, teaching such a thing does have a huge liberal bent.)
