If I am Vlade I would not take Doncic on a draft, let alone trade for him.
Doncic is a good player, do not get me wrong, but he is overrated and Kings already have what he can bring in Bogdan.
Thing with Doncic is that in my opinion he is already close to his ceiling and there are no areas where he can progress a lot. He already has good skills, good shooting, very mutere player with high BBIQ, already reached his physical limit more or less. One of the reasons why he is overrated is that his stats mainly come because Pablo Laso is just decent coach and only knows how to give ball to good players and let them do what they want. Which is a bad thing for developement of a player, but I will get to that.
Doncic knows to play only if he has a ball in his hands, and with Bogdan and Fox, Kings do not need that, they need more somebody who will feed of them and who can play even without ball in his hands. Second thing is that Doncic is a ball dominated SG primarily and he can not play on SF, I mean he can but like Bogdan, it is not his position.
Now to go back on player developement. Doncic is having more or less same numbers as Bogdan in his age in Euroleague, but because of different things. Than Bogdan went to Fenerbahce, and strugled at the begining, because he did not know how to play without beeing domanant player on a team. After a while he learned. Now Doncic might go through same process, where he finds himself in a position where he is not number 1 or number 2 guy, in a position where he is not primary ball, and question is can he play that kind of basketball.
So tu sum up, unless Kings get 7th or 8th pick with Doncic on the board, I would not take him. If you did not have Bogdan, yes, but with him already on roster, it would be better to focus on SF like Porter Jr. Unless you get high pick to get Ayton or Bagley.
