Nicknames are not guaranteed to be unique.
You can use the router fingerprint instead,
wherever it says to specify a nickname in the torrc manual.

https://www.torproject.org/svn/trunk/doc/spec/dir-spec.txt
"
   2.3. Nonterminals in router descriptors

      nickname ::= between 1 and 19 alphanumeric characters ([A-Za-z0-9]),
         case-insensitive.
      hexdigest ::= a '$', followed by 40 hexadecimal characters
         ([A-Fa-f0-9]). [Represents a server by the digest of its identity
         key.]

The above cited document describes in section 3.3 
how nickname-to-identity-key mappings are maintained
and how the Named flag could be conferred upon your router.
