Both the Hummel crew and Becker should have to secure their independance through Diet legislation. Under the proposed 14.3, PvP battles will still be possible in the post-cataclysm phase. If either of them fail to abide by whatever the Diet says, the Electors can always round up a 'posse' and go teach them a lesson. So, it seems to me that they should either be looking to secure a political agreement with enough powerful people to pass a vote, or they should be prepared to fight.
