Oritolon's biggest issue is lack of turnover. It's plain stagnant. Even when they do get new leaders they pretty much keep the status quo, or secretly plan on other things that never come to fruition.
What it needs is somebody to aggressively campaign whatever crazy policy to get support, but stay in line enough to avoid being a total pariah. Even then, two of their duchies are headed by the Old Guard.
Best way to do it would be to oust the old timers as traitors, after having some skilled assassins do some work. Just stab repeatedly.
