That is exactly what the egress routers in chapter 6 of my PhD do, but in a very controlled way -- by setting and clearing M_MCAST !

In Ch6, ILNPv6 packets are effective being routed, using a multicast next-hop address (as distinct from the destination I-LV, which in turn is distinct from an IPv6 destination -- it just uses the same format.)

It's counter-intuitive (and should not happen outside of that constrained scenario), but it has real world applications.
