Trade on a personal level

[lll Sir Haze lll]

I would like to propose the addition of trade to the game.
But not like CK2 Trade (although tradeposts and the like could still be added in some way/at some point of time)
But on a personal level.
Being able to exchange rights, lands, alliances, guardianship and gold. (And more)

For example:
My father died and now i inherited the kingdom of poland. But in succesion i "lost" a couple counties in my primary-duchy. Now some pesky vassals rebel, I surpress them and revoke their titles. It would be nice if i could:
Trade a county i revoked for a county in the duchy my capital belongs to. Maybe to sweeten the pot i could add money or a feudal right if the owner doesn't want to part with said county.

Other example. I am a vassal of the emperor of the HRE. He's bothering me to educate my son in his culture. I wanna be able to propose: I'll let you educate my child but only if you accept me having fortifacation rights.

Other example, I am bordering the pope, i wanna have someone excommunicated. I wouls like to be able to offer me swearing fealty to the pope in exchange for him excommunicating my rival.

Some of those things can be somewhat done with hooks already, but not in the capacity i would like them to

The diplomatic side of the game is tragically underdeveloped, in my opinion. Many other options would be needed, such as being able to negotiate an alliance without necessarily having to marry someone (and dissolve one without necessarily having to wait for someone to die).

Being able to do this would be great.

this would be perfect for how I would like to see marriage, so you could do different things then just getting an alliance; IMO the default should be non-aggression and you do these sort of diplomacy to get better deals.

For example, I am the duke of Prussia, I am pagan, and I am bordering a large and threatening Poland. The king of Poland has a young daughter and I don't have a wife. Now normally he wouldn't agree to the marriage, but I offer him a few things, notably I agree to be Christianized and perhaps agree to swear fealty to the king of Poland.

Or as another example, I am the powerful duke of York, and the King of England wants to marry my intelligent and beautiful sister. I could say no, however as a powerful duke, I want something out of this notably I want to either have low taxes or exempt from taxation. so the marriage goes through, my sister is now queen of England, and I as the duke of York now am free from paying the king taxes so I can fund my own projects.
