Individual cylinder smooth running control will be all over the place if you take that much weight out the flywheel, your idle is likely to be somewhat variable - it'll eventually smoothen out, but when falling back to idle after the controller has been initialised, it'll hunt and under/overshoot the idle setpoint. How fast the engine responds is realistically very little to do with the rotating inertia, there's so many other adjustments in the calibration which I've not seen many other tuners touch that control how rapidly the engine will increase and decrease speed with relation to the throttle pedal, they're pretty esoteric and complex to understand unless you're really looking for them.
The active surge suppression will also probably intervene quite a bit with that much weight off the flywheel, meaning it'll end up pulling power during fast torque transients due to oscillations in the drivetrain. You can certainly reduce the weight of the flywheel, but honestly, with adjustments in the calibration, the engine response can be changed way more than the flywheel will give you any day.
