Chalmers + two minimum contracts (say two of House, J.Howard and/or Magloire) would allow Miami to take back about $4.5 million worth of contract(s). They could also throw Dexter Pittman into the mix to get up to $5 million if necessary. That seems to be the ball park.
Also, Chalmers is in the final year of his contract. Miami is also sending their 2011, 2012, 2013 and 2015 first round draft picks to Toronto and Cleveland. So they don't have anything to offer up there either, as a further incentive. Just the $3 million in cash.
Not sure what that package is worth ... needs some thought.
Just looking through the list of teams ... I don't think they can get any upgrade at the point for that package.
Miami's only real hope would be some team (say Toronto) wanting to get rid of someone (say Jarrett Jack) to ease a problem (financial issues, minutes issues between two PGs, that type of thing) + there being a lack of suitable offers in the trade market. Both parts of that are, well, a bit wishy washy.
It looks very unlikely that Miami can anything done along those lines.

Best names I could come up with -- Randy Foye, Toney Douglas

I think the Heat would be better off packaging Chalmers and cash for a young wing player instead of a PG and moving Wade or LeBron into the PG position. Someone like Brandon Rush who is capable of playing of playing above average defense, above average rebounder and can shoot from the perimeter.
They need someone who can guard Ray Allen so that they can leave Dwyane Wade on him. Using this trade package for a young defensive wing who can shoot would be their best way to acquire that player.
