Would Steve nash be a good fit with the heat?

This suns team needs to start rebuilding honestly with old players in nash,grant,vince leading the way. We need younger players and steve nash will eventually need to go, do we trade him now while he is sitll valuable or try to build around him in phoenix? Would he work with the heat? I don't think so because the heat play tough physical defense, plus nash needs the ball to distribute which would render james or wade useless since they are not catch and shoot players. What ar eyour thoughts?
