You keep the core together and then go for Durant in 2 years. Keep Amir and PP (re-sign for 3 years) and then Amir walks after next year and Durant slides in at the 4 with PP.
GV and PP aren't going to command >5M a year.
I know people hate talking about "intangibles", but Vasquez keeps the confidence of this team sky high when they get down. He's a leader and gives it his all on every play.
