witchcraft, vampires and in vitro fertilization through surrogacy, After all, why didn't they ever resolve Rebekah's situation through this?

Could witches cast a spell that could remove eggs from a vampire (Caroline or Rebekah?) and fertilize those eggs through "in vitro fertilization", so that this possible vampire could have children through a surrogate mother? I know it's strange, but I'm not referring to the child being born a vampire or half-vampire (probably the vampire blood in the eggs or genetics could generate some mutation but it's very unlikely), but rather just being an egg frozen in the vampire's body, if removed it could be used, right? because I was thinking that Lizzie, Rebekah or any vampire could use witchcraft and science to do this procedure, to have biological children and the vampire blood would have no effect on the eggs since these eggs were in the bodies of these vampires and were only frozen by the transformation, I wonder how the writers never thought of that? All of Rebekah's drama would be resolved with science.
