Could this work??
Washington get Iggy to build up with Wall and possibly Young. While Jamison rides ship until his contract expires.
Philly gets expiring deal of Moon and Blatche as a possible piece to rebuild (If Collins gets him playing some D), obviously some picks would have to be thrown Philly's way.
Cleveland gets help at the SF position while Arenas could bring some excitement to the Cleveland fans as he would be the man, and at only 28, could regain "most" of his form back.
Kings gets Mo Williams who could stretch the floor and help Reke out.
