Pietrus and Gortat for Green(6m),Davis(4m),Bradley and picks
Looking at Phoenix and what they're doing, they're playing rebuilding mode and holding onto Nash. Green and Davis both would compliment their system as Davis could play C but still chuck up jumpers
For Boston, we get a better version of Perkins back in Gortat, and a 6th man willing to play D against the best player and take open shots.
Rondo, West
Ray, Wafer, Moore
Pierce, Pietrus, Gil
KG, JuJohnson
Gortat, JO, Murphy
And we'd still have the MLE(if it exists) to use on a better SG such as JR Smith or Jamal Crawford.
