The mica2, mica2dot, micaz and iris motes have hardware UIDs. That is, they are equipped with an integrated circuit (DS2401) that is programmed with a unique 64-bit identifier. You can access it through the HardwareId interface implemented by the SerialId component. Of course, there is no guarantee that any 16 bits of this UID will be unique. There is a chance though that you can find a nice hash function that works for your motes, and gives unique 16- bit addresses. Once you have a unique 16-bit address, nothing prevents you from setting TOS_LOCAL_ADDRESS to this value on startup.
There's even a TEP on how to access it (TEP 122), although I don't think that any platforms currently comply with 122.
