Try nesting the current Comp into a new Comp.

Duplicate the nested Comp.

Change the Rotation of the duplicate Comp to 180 degrees.

Apply Radial Wipe to the duplicate Comp and set the Radial Wipe properties as follows:

Transition Completion: 75%
Start Angle: 0x+224.0
Wipe Center: 960, 540 (or center value of the Comp)
Wipe: Clockwise
Feather: 150
