To make room for ? . . oh, I see the problem. Women's arms are built differently than men's arms to make room for the hips, they rest at a slightly outward angle instead of being straight. Just put in a bend at the elbows and you'll have plenty of room and you won't have to change the shoulders or upper arm angle at all.
I prefer #1 or 3 personally, with a preference towards #3. It's hard to be certain though, I'd need to see it in the intended environment to really know what would be best. If you were to put the hair back on them all and slap in a quick background map, things should be easier to see.
