If sakura was the one who stood up against pain instead of hinata it is wat likely could happen: of course sakura will be beaten down and stabed but i douth that would make naruto go nine tails,because the last time he did that he injured sakura,and also to him it would be like the battles they had faced before because when he learnt kakashi died he didnt go nine tails,pain would have captured naruto and naruto would not know the fourth hokage and every one would still be dead so am saying it is a good thing that hinata was the one that stood up and got injured,am not saying i liked the way she almost died
