Na', he wouldn't contemplate going to the Heat.
Higher chances of him playing for the Lakers, but I don't think he would go and do that... he might have at some point, but I think he changed his mind late in his career as he became more ingrained with the Celtics.
But if he want to the Lakers, I'll forgive him solely because he grew up a Lakers fan, so I can forgive that.
He goes to the Heat, particularly to play with LeBron and Wade... and he's dead to me.
