I've never heard of one but I suppose you could get one made if you really wanted one badly enough.

Sound expensive to have one off made.

Engine can 'spool up' (climb in RPMs) quicker?

On the other hand you loose some of the driveability since the engine will stall easier. Not something I would do on a vehicle driven on the street.

A lighter flywheel will make quite a difference in the same way lighter wheels do. Some explanations here:
http://www.w8ji.com/rotating_mass_acceleration.htm

There won't be power gained, but the car will accelerate faster as it it was lighter.

The heavier the car, the less the flywheel should be lightened. For road use, the flywheel can be lightened a bit, but not too much or taking off from a red light may be quite an exercise with the clutch pedal, especially with a taller rear end ratio.

Mark Bull (mkbull here?) made a run of steel flywheels a few years ago.  He might be a good person to talk to.
