I think this would require signature of the client on a configuration
message to the server, and the server must authorize that signature
first. And to have a signed encryption channel. Otherwise all sorts
of imposters could do bad things to the lengths.

Of course I would prefer this general solution case, as opposed to
running another Tor instance just for this configuration of a private
local onion.

There is probably some good utility in being able to set up two levels
of VPN depth per your needs (4 and 2 hop):
client node node node HS
client node HS

Both I2P and Phantom allow control over the paths you own.
But I don't believe anyone has yet thought of that you might own
both ends and want this kind of depth selection and authorization.

We can see interactive performance with SSH with the
standard Tor 4 hops to clearnet. And is usually not too nice.

I hope to test some clearnet 2 hop VPN service with double
encryption to feel that part.
