I think you will need remote forwarding as well.

The problem is then that 5920 is not free on the remote side. So, I
think you will have to change the send port of tightvnc (if it is 5920).

And that's just my guess (I have successfully done tunneling with
SSHTools but it was years ago).

It is much easier to use the openssh binaries for testing and to do some
experiments to find the correct port configuration.
