Its possible,and i can't think of anything else considering they haven't given her anything unique to begin with.
However if she needs chakra for this to work then she had plenty earlier on,in fact her power was multiplied by at least three folds according to kakashi statement about how much kurama's chakra felt like compared to normal chakra.
This means she was in a position to deal out three times as much damage she normally could and did nothing to help naruto earlier on.Kishi just makes her look stupid by trying to shoehorn spotlight on her all of a sudden.
