As we know, to obtain Rinnegan one must have Indra and Ashura`s chakra. Taking this into account, it could be considered that Rinnegan can be awakened from a normal eye or Sharingan, because the only condition here to possess Indra`s chakra. On the other hand, both Uchiha who have ever awakened Rinnegan had gone through all of Sharingan stages (including EMS) what eventually allowed them to get one.

So is the last stage of Sharingan really required to achieve a new step or due to Hagoromo`s chakra Rinnegan can be easily obtained? P.S. I don`t take into consideration Hagoromo`s case because his original eyes wasn`t shown in manga and is hardly considered as canon.
