As someone who has gone over the handlebars and landed on my chin due to trying to optimize improperly (and who grew up working in a machine shop and now has a PhD in Engineering) I would suggest that removing 2 of 3 pawls (or any, really) is exceptionally unwise.
I've also broken a dura ace cassette and it's pretty unnerving. If you're willing to risk 13 cracked teeth, and having the doc scrape the dirt out of your broken jawbone, or a broken neck, or your genitals bashed...
If the strength of materials were such that one pawl would hold, that's they way they would have designed it. In addition to leveling the stress on any individual pawl, having 3 of them offers some degree of fail-safety. If one breaks, the others catch you. If using grease instead of oil (the usual approach ) doesn't quiet the hub down enough, get another hub. It's really, really hard (and way more expensive) to get a lot of caps on your teeth as I did.
