Personally I wouldn't because in the wild west it was supposed to be the fastest guy who shot his enemies down... not the guy who could survive the most bullet wounds.
You COULD remove the +5 cap for the great toughness feat to try and make up for lack of armor.
The late Louis L'Amour made mention of a particular historical exception to that rule (though not as such) in one of his short story collections: Gabriel vs. Phy.
Joseph Phy and Pete Gabriel got along just fine until they chanced to run against each other for sheriff of a particular county whose name eludes me. Big mouths on both sides of the campaign egged the issue on, even after Gabriel won the election, and finally they simply had to have it out.
When they met in the street, Joe Phy drew more quickly, and shot extremely accurately. He emptied his five shots into Gabriel's chest, all of them inside the outline of his opponent's front shirt pocket.
Pete Gabriel, well known as a very tough man, fired only one shot, killing Phy, and walked away to live a number of years afterwards.
Worth noting as well was the advice of Wyatt Earp: "Take your time, but take your time quickly." Because of adrenaline, you'll be moving incredibly fast, but your accuracy won't be so good because of muscle tremors. Get yout weapon out, steady your aim, and THEN fire. Having six shots in a revolver doesn't mean much if you get a good yank out of the holster and then proceed to miss three times. If your opponent doesn't, it's likely you'll never get any more shots.
Personally, I would keep the escalating Toughness save bonus. There's more than one kind of combat in the Wild West, and sometimes you need more than speed to come out on top. Although you might adjust the scale so that the bonus advances more slowly. I've done this with a couple of games.
