Theoretically, there really is no mechanical disadvantage to a lightweight flywheel in a vehicle. The only reason stock flywheels weigh as much as they do is because the manufacturer decided that is the weight that would provide the optimal balance between efficiency and ease of shifting for the average driver.

he's meaning if you were to let off of the clutch slowly it wouldn't have enough rotational force, so the engine would die instead of pulling the car...like a stock one does.
the whole rotational force thing is what comes into play. im sure on throttle response you'd feel it right off, but inbetween shifting i bet your car would quickly drop as it doesn't have that extra weight to keep it spinning.
try thinking of it like this, hang a paper plate up on the wall by its center with a bolt and spin it, then hang your flywheel on the wall in spin it. one is going to stay spinning longer than the other, but one will take more force to move initially.
also there have been horror stories of aluminum flywheels cutting people's feet off, probably because of the whole heating up and cooling down at different temperatures.
