The whole idea is predicated on exactly the technocratic, 'nanny knows best' principle that the Brexit vote rejected. It is essentially a recipe for nothing ever changing.
It's also utterly impractical. Look at Scotland. I defy you to try and keep Scotland in the Union on the basis of a 59:41 vote in favour of independence.

As to the second vote idea - besides the logistical and legal issues - I see no practical merit in it.
Your original contention was that shifting the margin of victory would be arbitrary (which of course it would). I maintain that the current system is even more arbitrary for the reason I've stated: that a 51-49 vote is no more meanintful in terms of representing the "majority" opinion than a toss of the coin would be. A 60-40 vote would be significantly more meaningful as it would prove that a majority opinion does exist.
