Given that hosters of a VPS often gives a big /48, /56 or /64 ipv6 subnet to a VPS I do wonder if the BridgeLine for ipv6 could benefit from that? With ip6tables -t nat -I PREROUTING -p tcp -j DNAT --to-destination [obfs4 address] /usr/sbin/ip6tables-save > /etc/iptables/rules.v6 all incoming TCPv6 packets would be flow to the bridge address. This idea is implemented in [1]. BTW there I do change the factory default ipv6 address into a random one too.
