It would be great if choji learnt the 8 gates technique & the strong fist style ..... Also , he can help completely unseal the reibi & fix its flaws , darkness and negative chakra ..... He could also learn the summoning technique , and learn sage mode from his summining clan ..... I think that would help the snake leech reibi to fix its flaws and reach its own sage mode ......maybe eternal sage mode and help choji by gathering nature chakra ....
