I've seen that often enough -- except the other way, with appliances fitted with Australian/Chinese plugs twisted so that the pins will fit the American style sockets.
There are plugs out there, made by one of the many "China National" (gov't owned companies), where the pins are on little rotating supports.
This allows you to position the pins so that they are parallel (for American style sockets) or crow-footed (for Aussie sockets).
These are two-pin plugs only, obviously.
I have one of these plugs at home -- they're not sold here in the USA unfortunately. I managed to "coax" it as a sample from the manufacturer.
Construction, however is flimsy. But the concept would be a neat idea. Now if some reputable manufacturer would take the idea nd run with it?
