I don't think you could do that without special support from the
container. For MultiIndex you could implement a new index type. It
could possibly reuse this implementation if it had some sort of
ownership policy but MultiIndex normally implements that kind of thing
itself.
I can't see any benefit from Intrusive in this case. There are no
collisions so there's no need to do anything like chaining the
elements.
