IRS2092S Pin 2 GND

Working with a IRS2092S based amp and I want to modify it to accept non inverting signals. Pin 2 is marked as the + input and is normally grounded. Can I lift the ground with say a 100 ohm resister to ground and then use pin 2 as a non inverting input or am I missing something. It does state in the datasheet that the COMP and protect circuit reference the ground from pin 2.
