Responding to this topic specifically:

All root server operators have made a strong commitment to only serving
the DNS root as managed by IANA [1], I'm afraid this option is off the
table.  Although you could use some wiggle-ling to try and say this
principle doesn't apply to "old addresses", I would not be willing to
take that wiggle on behalf of b.root-servers.net.
