I would say that there should be a Slug Sage Mode. Then like how you combine Senju/Uzumaki and Uchiha, when you combine/master the three Sage Modes (Toad/Snake/Slug), you can manifest a Sage Mode that's equal to that of Rinnegan, with a Chakra Mode and Truth Seeking Balls and all, but is not the Six Paths Senjutsu, as the Six Paths Senjutsu is passed down from Kaguya, and the other Sage Modes are passed down directly from the Shinju (maybe, because there's already natural energy on Earth before Kaguya came, and it's stated that the Shinju has natural energy, so I'm assuming that the natural energy originated from the Shinju).
