Mugger sounds interesting, but I'm not sure how easy it would be to add in a conversation option to each person. If there was a mass "add to all" option, that would cause problems too such as mugging Alexandar at the end. Additionally, it sounds like "give me your stuff or I'll attack you" sounds like that should probably not work on everyone. If you try to mug a guard or someone tough or someone higher level, they should just kick your ass - realistically speaking.
