I _think_ that is what gnunet-peerinfo should be used for.
You can get a hello uri like this:

$ gnunet-peerinfo -sg

and (not tried) "load" it at another peer using

$ gnunet-peerinfo -p $URI

Yeah. I briefly checked the code and it is not clear to me that own own
hello is in the peerinfo database. And only those seem to get
published. Maybe you can add your own to the database as above?

Yes. That is gnunet.org and its hello is shipped (as a file) with any
gnunet installation.
If that peer is not your friend, no connection should happen though.
