The children of such a marriage might be, as we hope all children will be, a testimony to their parents' enduring love. But they could just as well be no more than a dynastic necessity. For most of history there has been no choice. And a cloned child is not a reincarnation or a recreation of the original but another unique human. Clones are not the same as each other any more than identical twins are, in fact they would be much less like each other than identical twins, since not only would they have slightly different DNA, but they would also and more importantly have grown in different wombs.
Cloning is hugely wasteful.
Dolly was the only survivor of 347 embryos, many of which were aborted in late pregnancy. If this plan goes through, many of the surrogate mothers will suffer horrible miscarriages - for nothing but a cult leader's megalomania. Perhaps the only worse outcome would be for the project to result in two babies being born.
