How, exactly, would you turn those into part of an IPv6 address?
UTF-8? ASCII? if you go with a custom encoding and do 0-9,a-z, plus a few symbols you can get 6 bits per char for a grand total of 10 chars squeezed into 8 octets.
Any other address class will work well, but I'd rather not use reserved space outside of GUA, ULA our LLA scopes to avoid bug-hunting on poorly implemented IPv6 stacks.

However, I still think GUA is the best, most flexible choice.
This brings up the question of "what is outside of LLA scope" - to my mind it's everything outside of fe80::/10 - in reality, there's that unfortunate tendency for it to be considered fe80::/64 when it comes down to implementation. Regards, Oliver
