According to Madara [based on a tablet rewritten by Black Zetsu, Kaguya's will], the Sharingan-powered Rinnegan, which Madara awakened, only comes forth from those who already possesses the Rinnegan. Is it not, then, possible that Kaguya also began with Sharingan and progressed to her Rinnegan? After all, Sasuke's Rinnegan is virtually the same as Kaguya's (minus three tomoe) and awakened from his Sharingan when he gained Hagoromo's power. Read my comment again, I edited it a little bit, lol. So maybe the Sharingan and Rinnegan came at the same time due to Kaguya's third eye. And no, it isn't possible. Kaguya was a special case. Just like Hagoromo was. He was the only one to use a TSBs without being a jinchuuriki. Orochimaru and Kabuto had no knowledge of Kaguya's existence, therefore their theory only applied to Rinnegan with Hagoromo's influence. And Sasuke's Rinnegan is not the same as Kaguya, it may have three less tomoe, but you have forgotton that it is light purple like Hagoromo's.
