For me it seems that it is straightforward to modify an ssh client to 
allow to forward local ports to input/output of remote process instead 
of remote port. With such port-to-process forwarding in place I can then 
  start smbd in the same way as inetd can do it.

Then I configure smbd to write all logs etc. to files in the home 
directory with a guest read/write share pointing to the whole 
filesystem. Yes, it is a lot of work, but so far I did not loose an 
interest to play with ssh.
