MP7758 Bridged Mono Out

I want to drive an 8 ohm load at precisely 20W. The datasheet gives 0.8V PLIMIT as 5W output for a single channel.

If the same mono input signal was fed to both L and R inputs, could the 8 ohm load be driven to 20W (4 * 5W) at 0.8V PLIMIT by connecting across 1A and 2B output while sending 1B and 2A to GND?
