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).
