Of course you can do. You need to install Tor manually and do some configuration. But this is complicated as I know. You may just install our Tor firmware and have a check. When you move the switch to the right side the devices behind the router does not go through Tor. But the router itself is still connected to Tor.

So next step is to make you ssh goes through Tor. This can be done but frankly speaking I am not sure how exactly to do that. Seems you are doing something quite unique.
