Maybe. Exum's value is really low right now. I think he'd be seen as low-lottery value. Wiggins was traded for an all-star. That was a bit of an unusual deal. Cleveland didn't want to give him up, but LBJ insisted. The #3 pick was used by Brooklyn to get Deron. Again, an all-star.
What Philadelphia needs MOST is a PG. They're in position to get one. I don't see them giving up the #2. Jazz MIGHT be able to trade a ton of picks/players to get to #4. I think that's the highest they could get. It's very unlikely Okafor, Towns or Russell are traded. Those are pretty much the consensus top-3, with a sizable gap to the next group.
