Ino's mind transfer, according to Naruto, was even faster than his speed in Bijuu mode. (Chapter 611) She should have no problem hiding away somewhere and using it on Sasori. She would then control sasori's body, take out the heart, throw it on to the ground, return to her body, and go stab the heart with a kunai.
Hinata could use chakra shrouds to defend herself from Sasori's needles and what not, so no posion would get to her. She can repel attacks with air palm and destroy Sasori's puppet threads with Gentle fist. Air palm could also be used to attack his puppet heart from afar, or she could combine 64 palms and twin lion fists to destroy all his puppets. Not to mention her Six paths chakra boosts her speed and power considerably.
