I know this would be something way down the line-- but perhaps an option during character creation for personality such as laid back, professional, stern, guarded, formal? These choices could effect the way the character stands with their weapon in towns. For instance, a laid back lancer could cross the shaft of their pole-arm over their shoulders lazily-- while someone guarded would hold their weapon in more of a 'present arms' manner. Maybe someone formal would use it like a walking stick? Just a suggestion. The same could be done for other classes as well.
