Well let's think about this, Lee most likely has improved significantly since the chuunin exams when he opened the 5th gate, so there's that. Neji and Hinata both have succeeded in mastering the Byakugan quite well, and their usage of the gentle fist is incredibly advanced. Ino and Sakura are generally weak, but they are very useful as far as healing goes. Shikamaru is a genius, simple as that. So the moment he figures out Sasukes abilities and limits, his mind will be scratching away at setting up a flawless strategy. Choji has advanced incredibly much, and now that he's able to achieve that "butterfly mode", he should put up a great fight. Shino and his bugs have always been a bit of a mystery, but from what we've seen, he knows how to use them extremely well. So considering that we've never really seen Shino be pushed to the edge, we don't even know how strong he is. Kiba and Akamaru as a tag team are a duo to be reckoned with, and their offensive prowess is nothing to be laughed at. And Sai, offers multiple long range attacks, along with some close range with his sword. All of this culminated is more than enough for Sasuke to be able to handle, there's no way he'd come out on top. But there definitely would be some casualties on the Konoha 11 side as well.
