Would it be at all feasible to give turbines/steam engines inertia?
As in; a turbine would "spool" up and down over a set period rather than instantly starting or stopping?

Would it also be possible to extend the range of sound pitching beyond just the 50-80% speed range?

You might want to look at the RealisticReactors/RealisticReactors+ mods.
They both add inertia - just not to the turbines but to the reactors themselves. The "plus" version also has control rods which allow your reactor to become uncontrollable under some conditions.
