What little I know of both, makes me think they are in the overkill
category and possibly non-compatible on the same http_port.
  WCCP being a silent? router redirection to a squid machine.
  TProxy being a silent local-machine interception and spoof.

I don;t know enough details of wccp to be certain of this. But;
By the time it get to local machines tproxy the traffic has already been
wccp re-routed from its original track and I would not expect tproxy to
work on it properly. I would expect to see squid spoofing the routers
address as source on outgoing requests instead of the client which
tproxy should spoof.

tproxy4+ support has not yet been added to either version of squid.
Henrik points out it should be easy, just nobody has had time or
inclination to look at it yet.
