This thread is cute, but to just appease my curious side, I'm gonna try to play along. I'm assuming this guy would use Bard if he wants to make a range tank. So, let's take a look at the gear available at the end of the game. To optimize vitality, I'd suggest using ilvl 130 Augmented Ironworks gear, and Iolite trinkets stacked with Vitality first, and Determination second. The reason I suggest Iolite is because of the other aspect of tanking, agro generation. Since as a Bard, you have no additional enmity generating skills, you're out of luck if you can't dish out some serious damage. So you will have to balance Dexterity with Vitality on the Trinkets. So... what do we end up with? A Bard with about 7, 7.5k hp, lower damage than any other dps who went all out damage, no enmity generating skills, no real good mitigation cooldowns, and pitiful armor rating... need I say more? Leave the tanking to the heavy armor classes that mitigate physical and magical damage in spades.
