all of that is an iffy situation. there is no proof that Orochimaru could have even handled the power of the Rinnegan. Obito who was not only an uchiha  but also had hashirama's cells inside him had a hard time controlling a single Rinnegan. all of that genetic tinkering orochimaru did might very well made it even more difficult for him to use the Rinnegan because not all that DNA might be compatable
