You don't need a BNG. You need an L3 switch as the first hop the customer 
is talking to.

If you have L3-in-vlan-per-customer at the first hop then you don't really 
need all of that. If you include rudimentary VRF support then you can even 
support wholesale. /64 per customer, DHCPv6(-PD) server support in the L3 
switch and you're good to go. There is equipment that already claim to do 
this (I never got to test their implementation based on my requirements 
because I switched jobs, but they claimed to have implemented everything 
last year).
