I'd take Tyreke Evans for Derozan
Tyreke evans is a real good player. His stock is low because Isaiah Thomas took the PG spot and the Kings are forcing him to play the SF.
Tyreke Evans for Derozan is a steal ... you can easily throw in a 2nd rounder as well.
to make salaries match, Tyreke Evans + Jimmer for Derozan + Amir Johnson works. Jimmer can play the role of a Barbosa. Would be better if they include Terrence Williams instead of Jimmer, but they probably won't. Amir is redundant with Ed Davis.
Or maybe sign and trade Bayless, and package him with Derozan to get Tyreke Evans and Terrence Williams. Jose can surely backup Tyreke.
