with max rev well after the 80 kts call.
A pointless exercise if you don't mind me saying so, all you will achieve is a lot more noise, increased risk of FOD and higher Tats. Reverse is most efficient immediately after touchdown and efficiency diminishes as ground speed diminishes.
I wouldn't reduce AB below 1 for the conditions you describe, probably not below 2 in practice. The AB is there for a purpose, it is more efficient than the human at rapidly applying pressure and modulating it as GS reduces(Those are Boeing's words, not mine, I just agree!).
