My plan A would be a blockbuster with Philly around Kemba and Simmons. I'd consider 3 different trade packages.
package #1Kemba + pick(s) + non-core player(s)* for Simmons + filler (if necessary)
* non-core players = Theis, Kanter, Langford, G-Will, Timelord, Semi, Edwards
For instance

Smart - Brown - Hayward - Tatum - Simmons
package #2Kemba + Hayward for Simmons + Horford
https://tradenba.com/trades/VO5e6Kz1IObviously, Horford's contract sucks big time. Not sure whether I'd pull the trigger.
C's lineup after the trade:
Smart - Brown - Tatum - Simmons - Horford
package #3Kemba + Hayward for Simmons + Tobias
