I would take wednesday and do:
Cleans, dead lifts, legs press, hamstrings
Squats, Lunges, leg extensions
Start one of your push days with over head press
Start the other with a bench (or incline) press
Unless you cannot train thursday, I suggest taking a day off after each 3 day period. Better yet, I would suggest training 2 on, 1 off, using that scheme.
Mobility drills, face pulls, external rotations, abductor work, and various planks for core.
