There's no realistic combination of players that would convince Danny to give up the pick, considering your hypothetical has it becoming the #1 selection. Hezonja, Gordon and 2016 ORL 1 would probably get him thinking, but I can't see him passing up a shot at Simmons for second and third tier prospects.
edit: On second thought, if Philly had the 2nd or 3rd pick and was willing to hand over their pick + Okafor, that also would be intriguing, but I still don't think Danny would bite.
