The other guys managed to design one with a < 3mm profile. It should be possible, shouldn't it?
The big problem would be with the voltage. But it looks like the USB-3.1 spec supports 20 volts (same as the 85W brick that comes with high end MBPs), and the mac power bricks only send 3-7V until they've had a handshake with the computer.
So it seems at least within the realm of physics that you could make a dongle about the size of the old magsafe-1 to magsafe-2 adapter...
