Brian,
I would never dispute the voracity of your argument re bank angles and limitations, though perhaps some better qualified than me might, I'm a bit curious as to what these "baffles" are in the fuel tanks. I spent the early part of my career on the tank team at Colerne, as you know, and can remember no "baffles" in the main tanks, just struts and sealed wing structure. Are you referring to the baffles in the external tanks ? Fore and Aft, designed to prevent large changes of trim during steep climb and descent ? If so, I suspect that such displays were flown with external and aux tanks empty.
