How about *configuring* the clients so they use the proxy "properly" instead of doing transparent redirection? Then you can keep the Squid box on the same subnet as the clients, and still block people trying to do TCP port 80 straight through the firewall (only one source IP is allowed - the Squid box). You also get the benefit that they can do FTP over HTTP proxying too, which you can't do transparently...
