I guess you think in case of an engine failure people use the rudder input to see what engine failed. But there have been plenty of engine failures where the pilots shut down the wrong engine. And the pilot not flying should always confirm what engine is failed. Guess what he uses....
The Cessna CJ uses bleed differential to add rudder bias for an engine failure, so when you have an engine failure you step deeper into the pedal on the working engine slide. Takes 10 minutes in the SIM to get used to, and same to get unused to.
Boeing already has that on the 777 and 787. It's called TAC (Thrust Asymmetry Compensation)..
Airbus doesn't have manual aileron trim because in normal law, it does it automatically (to some extent) when an engine fails
