Bulls gets young player in Kuminga who is just 22 years old & he can be amazing with Giddey & Matas. They only give up expiring Vucevic contract, two second round picks & portland lottery protected pick (which most likely will not be conveyed)
Warriors if they do not get any other stars like Markkanen, Turner, Zubac, Sabonis or Giannis (most likely not) just send a player who Kerr do not trust to be in rotation for Vucevic who can space the floor & score. Also you get two second round picks & maybe if lucky portland makes play off via play in you get 16-18th pick this year and also you clear cap space, you can resign Vucevic for cheap & sign better free agents.
