Ten Tails IS Senjutsu basically. Becoming a TTJ you automatically get Senjutsu. Once you add Senjutsu to SPC, it becomes SPSC. The Rinnegan was already set to awaken eventually for Sasuke, since Kabuto literally repaired his heart by pumping Hashirama cells into the wound, and using Medical Ninjutsu at the same time. Half of Hag's own pure and huge chakra that he gifted Sasuke himself simply boosted the process and somehow changed Sasuke's Normal Rinnegan into a one-eyed Tomoe Rinnegan.. which is Sasuke's Left Rinnegan combined with his EMS and making it awaken right then and there while giving Sasuke a temporary boost so he can fight against Madara. Some things are more simple and we don't need to dig so deep to look for tedious info that isn't there.
