I like the idea, though it's probably a little too much for Philly and definitely not enough for New York.
You'd probably have to reroute Young to New York to give them a good wing prospect to build around, along with giving them either one of the Brooklyn picks or our 2017 pick, which they can switch with Brooklyn.
So it'd be something like this:
To Philadelphia: Terry Rozier, Jared Sullinger, Boston first this year, Philly's own 2nd (via Boston)
To New York: David Lee, Evan Turner, Tyler Zeller, Young, Maverick first this year, Minnesota first (probably two seconds), and Boston first in 2017
To Boston: Carmelo Anthony, Nerlens Noel.
I love that small-ball lineup, though. That surrounds Noel with 4 above average shooters, while also keeping probably a top-5 defensive unit in the league.
I would do that in a heartbeat.
