Nope. Slipper clutch has been successfully fitted to a 4th gen VFR. I don't think that's what is really going to help.
Leaving half the butterflies off from the other is going to make the engine run uneven and probably really poor in general. You should just increase the idle if that's how you want to go about it.
Of course, the absolute simplest solution is to stay in a higher gear, or just pull the clutch in, or not let off the throttle as much. All things you can do right now, no downpayment or modification necessary.
