Besides, Hagoromo was involved with Sasuke's Rinnegan, so it's without a doubt that whatever worked for Madara wouldn't automatically work for Sasuke. we cant be absolutely sure about that,

didnt madara say that near the end of his life hegained the rinnegan?

and conveniently sasuke was in the same condition while being treated with hashi cells, maybe the time wasnt the factor that lead to the rinnegan awakening but the body coming closer to death :/
