Let me see... you have spent years planning the invasion of Europe to the nth degree, had shore parties checking beach composition, sand / shingle, gradients for beaching landing craft and exiting tanks and wheleed vehicles from the beaches, designed funnies to flail for mines or lay giant fabric pathways across the sand, etc. - and now you intend to change the geography a couple of hours before the troops are due to land?
Have you ever considered a staff role with the IJN?
