I imagine Naruto and Hinata jumping in Juubi's direction. Hinata uses Byakugan and sees some weak point, some point of junction of chakra that if it is attacked alters the flow, making Obito e Madara lose control over Juubi... then they attack!!! (with help of the alliance)

OR

She will see the bijuus trapped inside the Juubi, still with their personalities because of the incomplete process, and Naruto starting to think how to release them, and maybe Kurama find a way to talk to them.
