Idea would be to stock up some of the Heat's draft picks and enable them to shop Jimmy Butler for additional immediate help and picks while staying competitive (also save $6M next year with Payton's more expensive expiring contract over Richardson's).
Warriors get their secondary scorer in Barrett at the cost of just Kuminga/Wiggins and a late first/early second pick swap + a 2nd to the Heat.
Raptors get a bounty for Barrett (Herro, Kuminga, Ware) and could potentially keep their first rounder if they tank the rest of this season.
