That is a pretty wild hypothesis, but I would have to say that when we are at the point of editing genes to get rid of debilitating diseases then sign me up.
I am very happy the way I am right now, but given the choice then of course I would choose to be able-bodied. It would be asinine for me to think otherwise.
So yes, if we could get to the point where we are editing the genes of something in a test tube could not survive outside of that test tube that then might potentially go on to be a human then it is incumbent upon us to make sure they are healthy as much as we can.
If that makes any sense!
