Here are some deals that would work (not saying they'd be done):

Sheed/Kwame/Herrmann for Miller/SAR (would get them 18 mil more in space next year)
AI for Howard/Dampier (Damp would expire in 2011 and we'd still have Bosh money)
AI for Bell/Morrison/May
AI/Max or Amir for Tmac/Battier

These deals all keep space for Bosh. Most of those players would not be retained past 2010 (Battier and Dampier are the only deals longer)
