When you create monks, they almost always seem the same. It's very difficult to role play different monk orders simply because monks don't have many options. I think it would be a great idea if monks could choose their order from a list the same way a cleric would choose their domain upon creation. These orders would give monks. Bonuses and penalties depending of the order. Such as the peace bringers, they aren't allowed to use quivering palm on the living like normal monks, yet unlike normal monks they can use quivering palm on the undead. I think it would add lots of diversity into to class the same way clerics are used. We can also go so far as too use the class restrictions from the books. If I could code I would most definitely start working on this right away. What do you guys think?
Not sure if it's doable the way you want it; what I'm going to try is to make the various Orders Prestige Classes (the Order of the Sun Soul already has one that I can use as a template) and give Monks feats that enable them to take a particular Prestige Class. That should give you pretty much the effect you're looking for.
