Obviously Mills for Ariza would be ideal, but the Spurs wouldn't do it. The Suns might, but would probably want a minor asset attached.
Bertans, Belinelli and Pondexter works. Already loaded with youth, in desperate need of 3-point shooting and basically done with Anderson already, the Suns might do this, with the idea being Bertans would be more valuable than something like a 2nd round pick or two.
Unless Pop actually plans to give Bertans a consistent role going forward (doubtful), Spurs might have interest too. Sign Babbitt as a replacement . . .
