What's the weakest point on the 18K B&W? I've never taken one apart, but I suspect it will be the material around the pins that allow fore/aft tilting. if you can pull two pins and take the head off then only those two pins are holding the head in place. How big the rest of the hitch is doesn't matter at all.
The pins carry no load whatsoever. The head of the hitch has female cylindrical profile sections that engage male cylindrical profile sections (with a thermoplastic bearing surface) on the uprights when the head is set in place. The pins merely fit below the male cylindrical profile sections to prevent the head from being removed even if the head release handles are pulled. That's why the pins can be padlocked to "prevent" the head from being stolen (as with all locks, they only keep honest people honest.)
