Wouldn't solve the problem. Basically you need the integrated components to have shorter transition times. These are an inherent property of the component: speeding up the transition time basically means "replace this component with a different component that has a shorter transition time"
As they say, "the candle that burns twice as bright burns half as long", or, in this case, "the transistor that runs at thrice the voltage runs for about 1.3 seconds"
