Your argument falls apart in the fact that Madara didn't have 6PSM despite having Sage Mode and Hagoromos chakra.

It also fall apart when the Sharingan is what is effected by Hagoromos chakra in an Uchiha. Indra and his bloodline have the eyes. That is why their eyes change in response to the addition of Ashuras chakra.

It falls apart some more when Madara has Hashirama DNA implanted into his body. So he does have the body of Ashura.

It falls apart even more when Nagato had the Rinnegan for years but never displayed ANY form of senjutsu. Not regular Sage Mode, not 6 Paths Sage Mode, not even Sage Transformation. He didn't get any 6 Paths Sage mode when he absorbed Narutos sage chakra.

And to take the cake, your theory doesn't work when Hagoromo gave Ashura power and he STILL didn't have the Rinnegan.

You also seem to forget that Hagoromo can grant specific abilities if he so chooses.
