Making something as good or better then the TC Electronic Infinite Sample Sustainer Pedal control settings minus the reverb seems pretty plausible as we now have a reverse feature on the maestro.
Infinite sustain is a great accompaniment and it may still allow you to overdub on top of that single track? Adding another element of recording to the aeros.

If the software allows you to do poly tuning you have 6 screens.
Yes would be used all the time.
Both would also save insane space on the board and add a lot more selling power for getting the maestro
