It's a very good question.
Chances are, probably not.
I've got to think either resigning in New York or going to play with the Lakers next year would be more appealing to him than coming to Boston.
Remember, the Lakers will likely still have Kobe. Even though he's not getting younger, I am sure players would still love to play with him (except maybe Dwight.)
I think the ONLY way Melo to Boston could be swung is if the Knicks get wind that Melo won't stick around, and the Celts offer the Knicks a package centered around Jeff Green
(like you mentioned.)
Then Melo gets dealt here from New York and then maybe he likes being in Boston and would want to stick around with Rondo.
Would love to see it happen. I think Rondo and Melo would be a very good 1-2 punch.
The other way that Danny could also possibly influence this is if the Celts deal for Amare's contract, as has been speculated on this blog.
If the Celts land Amar'e in a deal and he likes it here, would that convince his friend to want to come play here too?
Btw, Humphries for Amar'e checks out on nba real gm trade checker.
