Airspeed determination by gas turbine engine

Failures in airspeed measurements are increasingly implicated in aircraft upsets.

Am I right that it would be feasible to obtain a reliable (if not extremely accurate) airspeed measurement from a gas turbine engine, derived from some of its existing pressure and rotational speed sensors, under the assumption that the blades did not suddenly break?

[edit: since there are at least two such engines on commercial airliners, we have some built-in redundancy; the idea is is of course to feed this to HAL as a substitute for iced pitots]
