Revitalizing the Rheinland economy in some way could come handy. Rheinland is already in a good relation with Kusari, Kusari with Gallia, and even despite the distance, there has been some RP about opening up connections between Gallia and Rheinland. I'm sure Rheinland got a lot of resources to offer while Gallia is pretty much in need of that, and from more commerce happening between the two even Kusari could profit. The three houses could form a nice trade alliance at least, which could become a bit more later. Not saying repairing the gates would be one of the first stuff to happen in this chain of events, but chosing a goal like this could definitely align Rheinland towards rebuilding their economy. And in the meanwhile Rheinland authorities could have a new frontier in the Omegas against Corsairs and Hessians while trying to secure the resources they intend to trade with, not letting RNC caps collecting dust due to lack of Texas raids.
