As folk know, I don't have a five speeder, but version 2 is far away the most attractive. How about approaching Morgan on this? You may find they are happy to licence the logo as it's a not for profit undertaking with a very clearly defined market of people who have already bought cars.
It needs records keeping and the badge belongs to the car - not the person. Two and three speeders often have fitted the club replica badge as in the past, folk would sell the car and keep the badge.
