So the question is of it is possible with stunnel to convert / wrap e.g. by users the UDP port 5093, to "convert" it to TCP e.g. 5555
stunnel does only TCP. socat *may* be able to do that conversion (it knows both UDP and TCP and the manpage doesn't seem to specifically rule the combo out, but I didn't try it), but I would expect the resulting packets to have subtle changes that the software might balk at. A *license* service *should* try to reject manipulated/simulated peers, after all. NATing UDP traffic to a different UDP port that the firewall lets pass would IMHO be preferable, followed by proper tunneling (which includes variants that are "not quite a VPN yet").
