"I would love to take credit for coming up with this ingenious method of approach style to reduce pilot workload, I however can not. But like you, I would love it if someone would show me and everyone else here a valid reason why differential thrust for landing should not be done. It is an aerodynamically safe maneuver for which I have never read an accident report stating, "differential thrust," as a cause."

As many have stated here, the valid and accepted reason is that it is not a recommended or authorized technique in any large jet. The reasons are many, but the bottom line is control both during and after touchdown.
I suggest you write Boeng and let them know of your opinion, perhaps they will hire you as a consultant. Perhaps not.

Sorry, but in that video a crab is carried into the approach and then partially removed to a wing low touchdown in almost every example. Some aircraft can't land in a crab or partial crab. None of them can roll down the runway in a crab, at least not under control or for very long.
