b. If the solid gasket will stop the anti-dive function, I can't imagine what else you would need to do.
c. Good reason? Can't think of much, besides losing a bunch of wheel travel that might come in handy if you happen to hit some bumps while braking. 8-[ If the front does not dive as much during braking, the forks will not change their angle as much, so steering will not change (due to the decreased fork angle). If at night, your headlight will also keep shining farther up the road for better visibility.
Actually, I understand your question about disabling it, I just can't understand why you would want to do it, unless it's not working right. And, based on previous posters, I am understanding that it has the capability to work relatively well. I know the system on my GoldWing works well, but that is a mechanical activation, not hydraulic, so it does not change the feel of the brakes, only how much the bike dives when braking.
