Well, they could always turn NA_3 into a tavern. Perhaps even a map similar to the tutorial single player map in warband. A track, shooting range, dueling area, and of course a giant tavern. Integrate the PW settings and you have localized chat, faction chat, and perhaps even dueling/trading chat. PW also has a cool way of dispensing weapons. How cool would it be if the shops you buy in the marketplace could actually appear in the duel server? Giving the players a chance to try out/test the weapons before buying them. Of course, I'm getting way ahead of myself.
