I think you're confused. Whatever IPv6 source address is in the outgoing packet from the CPE is bound 1:1 to the subscriber. You can't conceal the address of the subscriber, if you ever want to get any packets back. If you want to protect the privacy of individuals within the home (etc.) behind the CPE, you can use IPv6 privacy addresses. But the traffic will still be traceable back to the CPE, of course. I hope you aren't under the illusion that NAT44 in CPE provides any privacy.
