Well, I am very hopeful that the salvaged Corsair vessel will indeed not be targetted by Hessians, Bundschuh or the LWB, who are all known for attacking Corsairs on sight. I would suggest caution around Hessian bases especially.
About stopping house police and bounty hunters engaging Junkers: that is unfortunately beyond the scope of anything the Junker Union (or any Junker at all for the matter) could do. Liberty is taking a more aggressive stance towards us, and it's not really our fault. I myself have been targetted multiple times (by scores of insane pilots in New York especially) without committing an offense, although managed to escape. The Liberty Navy command might not condone these direct actions, but that is fact: Junkers are a target. I do not believe there is anything we can do to make Liberty not attack us aside from maintaining our ships outfitted in the most inconspicuous way possible. That includes dismounting all salvaged unlawful weapons before entering Liberty trade lanes and vicinity of Liberty bases. It might be a real drag to do so, but there is no other way. It's either that or risking banishment from the lawful enterprises of the house. I myself mount only civilian and junker weapons on my CSV-II and Liberty lawfuls seem to be fine with that. I believe the officials of house Rheinland and house Bretonia can be reasoned with to omit certain equipment choices however.
If for some inexplicable reason Liberty declares all Junkers hostile, remember that we still have access to Puerto Rico through the Lane Hackers guard system. I do not believe they would deny us access to our system through theirs if an explainable situation ever arised. We need not worry about that.
