Acceleration is a momentary thing, we'd have to poll the sensor very fast. That's why copters use Gyro data too.

The tacho signal will be your biggest problem, if you want to use it as closed-loop feedback.
Duet2 isn't capable to read fast signals from external sources.
You could probably use it as a sign of life signal or attach an external RPM meter?
