REMAKE/REMODEL: With three months before his arrival at Sony Music, speculators are speculating as to what specific changes Doug Morris will make, what the company will look like at that point and what duties he’ll assign key execs like heavy hitters Rob Stringer, Steve Barnett and L.A. Reid, who are expected to play significant roles in Morris’ hierarchy, and Simon Cowell, who is now one of the company’s biggest rainmakers. The future assignment of Clive Davis, though, remains unclear. (4/7a)
