Are you kidding? It was traumatic enough when we switched from cubits, scruples and fortnights. And what good is a system of measurement that you can't use to bamboozle customers? ("That's not an ounce, ma'am, that's a Troy ounce...") If we move to anything, it's going to be Donald Knuth's Potrzebie system (see http://en.wikipedia.org/wiki/Potrzebie http://en.wikipedia.org/wiki/Potrzebie). It seems more well thought out than most.
