I don't think it is possible, but I do not know why...
AFAIK transparent proxying in Linux is limited to redirecting all ports
to a given port another host. It is not possible for the proxy server to
tell, for instance what the original destination IP address was.
A transparent HTTP proxy relies on the server name HTTP1.1 request
field to determine what host the client really wanted to connect to.
(this has been tested with Pacific's transparent proxy).
