Clans switching sides imo doesn't even really make sense in this game since there is no need for such mechanic anymore, its an ancient way that was supposed to balance Warband.
I suggest making Clans changing side extremely rare and if a clan changes side every member should get "Traitor" trait.
What traitor trait should do is basicly remove any execution penalty you would get when you execute the traitor. This way executing is actually usable and clans switching sides is a rare thing. Traitor trait should also change the betrayer clans relations with every clan in the betrayed faction to -100.
