Ned Stark just needs to spend the North's war resources helping people and taking them to the wall, then just ask the Prussians to help the Northern soldiers with food and supplies out of their friendship and make some promises.

organizes a revolt in the Bolton territory, which appears to be formed only by people who want a better life, as in the other territories where the Prussian company has control, forcing the Boltons to act in a bloody way to suppress these revolts, causing so much chaos that it would force the Starks to intervene to prevent more deaths.

Due to these revolts in the Bolton territory, trade along the roads would be influenced, forcing other lords to ask Lord Stark to intervene in the matter.

makes the Finns recruit a veteran of Robert's rebellion and secretly help him form a group of rebels against the Boltons by bringing together people dissatisfied with their government, like what happens in the film Braveheart where the peasant William Wallace starts a rebellion against the Kingdom of England.

makes the Prussian king forgive Lothar with a royal pardon, Lothar hands over the Valyrian steel and the newly conquered territories and the king leaves him as guardian of the 3 cities in Essos.

Due to the previous chapters that showed that there were hundreds of thousands crossing from the Rios territory to Campina, I think the number he will have to banish is around 100,000 to 200,000, I doubt the patrol can maintain this population and the crown will have to pay for the new members.
