One way to keep large empires at bay would be to allow the vassals to invite foreigners into their faction under certain circumstances such as having an alliances.
Thats a good Point. There are probably more cases like that and if the faction have the backing of foreign realms it would make them quite a bit more powerful and thus harder to suppress.Historically the King of France encouraged the vassals of the Angevin empire to revolt.
Could start here: https://forum.paradoxplaza.com/forum/index.php?threads/ck3-dev-diary-1-dynasties-houses.1270519/I think somewhat it will be represented in CK3. Dynasty or house head can give commands to dynasty members even in other realms. Question is how much influence they have.
The house head have hook on the house members which can probably be used to get characters to join factions: https://forum.paradoxplaza.com/foru...emes-secrets-and-hooks.1289167/#post-26052038Would be nice to give instructions to dynasty members to start factions and plots in other realms to archive goals

Also should definitely be able to side with invading foreigners if we like them better, barring valid checks such as, I'm being ruled by a liege of a different religion and the invader - likely an adventurer is of my religion.
We should also be able to support peasant rebels, at least if they're not in our realm.
The game is about characters and more Active vassals make alot of sense, especially if they go with fewer but more powerful vassals as they seems to be doing. Ck2 vassals are too passive in my opinion and don't seems to care about anything other than opinion or so.
