The big issue and flaw is - besides Liberty that has a corrupt corporate police that shares law enforcement with house agencies and removing navy/lsf enforcement would break lore you are splitting a zero.
Gallia's police was deleted and is now part of navy IFF.
In Rheinland Bretonia and Kusari very little law enforcement is done in the first place, in some months this might drop to literal zero - this might *seem* like a good idea l, but e.g. forcing BAF fleet to let pass a convoy of 20 Cardamine smugglers going through their capital right past them without them being able to do anything would discourage what little, if any, usage of law enforcement is in those houses. They don't patrol now, you wouldn't see more bpa, you'd just see even an emptier house
