Actually, deployment is much easier as follows:

   existing client
   -> client forwarding tool on 127.0.0.1 port 53
   -> cache forwarding tool on cache IP address on another port
   -> existing cache on port 53

Both sides install new software, but there aren't any changes to the
existing software. The same approach also makes it fairly easy to deploy
client-cache security protocols.
