James Harden, Mo peterson, and a Pick for Iguodala.
Westbrook
Iggy
Durant

Westbrook

Iggy played great alongside Durant and Westbrook this summer; he's instantly a #3 guy on that team instead of a #1, and Green has range, Durant has serious range; Iggy and westbrook are the slashers with Ibaka/Collison/Krstic hitting their 15 footers or so.
Now this trade I really like. The Thunder won't do it, b/c they're pretty dead set on being just OK, but it does make sense for both teams. The Thunder get a premiere wing defender, someone to run w/ Westbrook and a legit second scoring option. If they could swing Jeff Green for a defensive PF/C we might actually have a team that could legitimately contend w/ the Lakers.
For the Sixers, they get a proven starter w/ potential for growth - not to mention he's a much better fit for Turner, provided you believe in him , a draft pick and you save 7 mil in payroll. Might need another team to sweeten the deal for the 6ers, but I think the principles here are really great.
That being said, again, the Thunder are going to sit on their hands til their numb.
EDIT: Seems like the Kings would be a logical trade partner for OKC
