About the only thing I can think of is to set up a "firewall" machine
which has two interfaces.  One of the interfaces gets hooked up to
the Internet with a legal address and the other hooked to your existing
network.  All Internet access would initially require logging into the
firewall machine and then going into the Internet.  Then you could
slowly start renumbering machines to legal addresses and setting up
the firewall to route between their new subnets and your old network.
