Here's an idea (it relies heavily on a sudden Deus Ex Machina, but then, that seems to describe the manga lately):

Kaguya possessed the Byakugan and the Rinnegan. (I know there's been rampant and heated debate on that, but Sasuke has the same eye and it's considered a Rinnegan, so what's good for the gander is good for the goose as far as I'm concerned.) We know that Hagaromo received her Rinnegan, albeit in an altered (perhaps diluted) form, and from there he passed it on to Indra, who diluted it still further into the Sharingan. But the Byakugan also manifested in the Hyuga clan, indicating they are related to Kaguya. I think they received the Byakugan from their founder- Hagaromo's brother, Hamura.

From there, we know that Hagaromo's chakra is still existent and even sentient, along with Kaguya's, Asura's, and Indra's. Logic would dictate, then, that Hamura's chakra is alive and hidden as well. And who is the logical host for this chakra? Hinata. Like Hamura, she was less talented than her older sibling, Negi, and yet is still a competent user in her own right. (She's also arguably the only real Byakugan user of any significance right now.) So, Hamura will manifest within Hinata, dusturbing her chakra and so allowing her to escape the Infinte Tsukuyomi; he'll also replenish her chakra reserves to counteract what Kaguya took. She then tries to reach Naruto.

Meanwhile, Naruto and Sasuke try to fight Kaguya, but (after several filler chapters needlessly stretching out the fight, naturally) Sasuke ultimately suffers a fatal injury, while Naruto ends up losing both eyes. With his dying breaths, Sasuke gives Naruto his Rinnegan, asking (a la Kakashi and Obito, which the former notes as he looks on) to become Naruto's eye and see the future with him (thus allowing Naruto to later become Hokage, as he had earned, while still technically allowing Sasuke to kind of be in that position as well). Hinata then arrives and, upon seeing Naruto's condition, insists on donating one of her own eyes, and with it, Hamura's chakra. Naruto will then have the chakra of all nine tailed beasts, both halves of Hagaromo's power, Hamura's chakra, Asura's and Indra's chakra, the Rinnegan, and the Byakugan, giving him enough powers and abilities to be able to face Kaguya and the Shinju within her. After some fighting, Naruto will then impale Kaguya's chest (as seems to be the trend in the last few chapters) and attempt to extract the Tailed Beasts from her. Within their subconscious, Naruto, Hagaromo, Hamura, Asura, Indra (the latter two having reconciled after Naruto and Sasuke fought together), and the Tailed Beasts will confront Kaguya and the Shinju. Gradually, they will convince Kaguya that her desire for peace and an allied army was already coming to light (citing the Shinobi Alliance). She will realize how wrong she was and, emulting her son, extracts the Tailed Beasts' chakra from herself and sets them free. Kaguya, Hagaromo, and Haruma will then decide together that the Shinobi world is better off without them, and all three will enter Madara's possesed body, and in an act of self-sacrifice, will use Creation of All Things to destroy Madara, themselves, and the Demonic Statue of the Outer Path simultaneously.
