When using a IRS2092 based class d amp in BTL, the 2 inputs are 180° out of phase. If I use 2 IRS2092 amps, using a 90° phase shifter on the inputs, what would the output phase be for the 2 amps? I'm trying to understand what the phase shift does to the output when the inputs are already 180° out of phase.

You need a 180 degree phase shift for the signal into the second amplifier.
This gives a voltage swing on full power from b+ to b-.
