Ok, so your question is if it is possible to proxy and have the proxy use
the same IP address as the client.

Yes this is possible, provided ALL return traffic to the clients is routed
via the proxy server. What you do is that you set up as many IP aliases as
you have clients on the proxy server using private IP addresses, then NAT
these back to the client IP addresses and create tcp_outgoing_address
rules assigning each client one of these private IP aliases.
