Even tough you have very good arguments, my suggestion would be to have a class A network (I got that right, right?) for all the users and only having 6rd as service on that network.
ARIN and IETF cooperated last year to allocate 100.64.0.0/10 for CGN use. See RFC 6598. This makes it possible to implement a CGN while conflicting with neither the user's RFC1918 activity nor the general Internet's use of assigned addresses. Hijacking a /8 somewhere instead is probably not a great move.
Ok. If I have calculated the netmasks right that would mean to set aside: 2001:0DB8:6440::/42 for the use of 6rd service: 2001:0DB8:6440:0000::/64 = 100.64.0.0 .... 2001:0DB8:647F:FFFF::/64 = 100.127.255.255 -- //fredan http://tlmc.fredan.se
