I don't see much benefit, you would lose damage overall to gain, maybe 20 res/str or dex/life? If you want a tankier version of a bowa you should use a mat bow, enables the use of only 44 ias instead of 95. That's just how I view it. On a gmb, I'd rather pump the raw damage potential while still getting 2k life before bo and 260 frw.

Edit: phone typing is shit.
