also another thing

If Naruto were to ever get the Rinnegan it would stand to reason he would need the EMS first.

its safe to assume that the only reason the uchiha have the weakness of going blind the uchiha only have the eyes of the sage and not his body. so wouldn't it be a logical assumption that if you had both the eyes and the body of the sage that it would naturally develop along the line of Sharingan>MS>EMS>Rinnegan while in the body of a senju. it may not say that it is possible but it says that both uchiha and senju power is required so my speculation is plausible
