Why do you feel the need to internally use /80s based on your public /64? You could choose any unused /48 and subnet it into /64s for your VLANs. Since you use NAT anyway, your internal addresses don't really matter.
The ND proxy solution (without NAT) is preferrable though.
While it's technically possible to use prefixes longer than /64, it's not recommended and issues are to be expected.
