As a theatre academic, I would be most excited with a RP group revolving around the Theatre of Dionysus. The group would be an immense resource to the city, providing entertainment and discussion items for events and religious ceremonies. We could have board-recreations of some of the famous Greek plays, with slight spinoffs to make them unique to our community here at AncientWorld. A 'green room' or 'skene' would provide the 'actors' with a place to discuss freely, and a thread could be dedicated to the creation of 'new' greek-themed works.
