I think it be more interesting seeing a shift to more revolutionary groups for alliegencies and seeing a clear divide from piracy and criminally aggressive groups since what you want to focus on political and social economic improvements to the civilians of Rheinland. Nice to see a faction that fights for the support of a regions populace instead of power, territory or money. Rheinland is needing a little jumpstart as it was only one of the few houses where its unlawful factions all bloomed from left-wing revolutionary backgrounds. Some went astray for ill-gotten-gains, while others stayed true to the effort of a revolution.
You would have figured the Unioners history within Rheinland being of concern to the LWB sect of the farmers alliance. Please don't gas your own supporting demographic.
Also i suggest working in something about the Civil War, I'd imagine the civil war did take a serious turn on Stuttgart. Potentially for the worst since the Imperialists were very much the authoritarian right-wing feudalist elements that subverted a (extremely corrupt) democratic republic? If its anything they fight about, maybe the authoritarian shift since the inclusion of the Imperials into Rheinland governance took toll on living standards and freedoms. Especially considering the historic economic divide between Royals and 'peasants'. Although I guess its upto you if those profits the imperials seized from synth foods in exchange to allow them to remain on the planet ever trickled down to the working class. (Big historical hint: They usually don't with Imperials.)
