Player Can Ally With Anyone
The player is extremely restricted with diplomacy, doubly so in multiplayer. This unrestricts the usual diplomacy options (peace, join war, non-aggression pact, military alliance, defensive alliance, military access), so now the player can have some sand in their sandbox.
Also works for multiplayer, now you two can create some unholy union that should never have been.
Update (27/06/20) – Now made it so that the AI can’t offer ending their vassalage. This is an attempt at avoiding a hard-coded rebellion with Empire vassals.

I recommend looking through my collection of campaign enhancement mods, as they all bring some much needed dynamism to the game: https://steamcommunity.com/sharedfiles/filedetails/?id=2101461335
