This is completely impossible. We're talking about America here: it's utterly impossible for America to look at other countries and just copy them. It doesn't matter how much sense it would make; if America has a choice between sticking with some brain-dead system (perhaps, a measurement system for instance), or adopting a very logical and sensible alternative that America didn't invent, America will stick with its own brain-dead system, and claim that the alternative somehow can't possibly work in America because America is "different" and "exceptional". The only way America will adopt something new and better is if it's invented in America.
