Sorry, Ricky. But that won't work. EUI-64 is required for autoconfig, 
and it expands the 48 bits to 64 bits by inserting FFFF or FFFE 
depending on if the original is a MAC-48 or EUI-48 identifier.

That being said, you might be able to use stateless with tokens which 
can be less than 64 bits, though not sure how well implementations will 
handle stateless autoconfig with less than a /64. You can also use 
DHCPv6 with TA/NA addresses, though Cisco doesn't support those options 
in their IOS implementation at this time, open source DHCPv6 servers do. 
You can also backup to static assignments.
