Naruto would have the complete Body of the Sage (full Juubi Jin, full Yang powers). He would have a more complete cloak, although it may not be exactly like Madara's.
The only power he wouldn't gain is the Sage's Yin powers / Doujutsu (such as Madara / Sasuke's Rinnegan). Naruto's Senjutsu chakra would be equal to Madara's.
However, Naruto seems to (in effect) have superior Yang powers already. This is probably a result of 1) being an true Ashura transmigrant with additional powers from Hagoromo himself, and 2) having access to the powers / assistance from the individual Bijuu, who grant him unique powers.
No, You need the complete rikudou chakra to gain a similar form to Juudara/so6p.
Naruto only has the yang power of the sage...
Well, I guess.the eye's/yin portion of hogoromo have nothing to do with how the jin's look. if that was the case, sasuke would have gotten an updated look after getting his rennigan, but that didn't happen. if he was to get the rest of the biju power from kaguya, i'm not sure what he would look like. his look doesn't seem like it has that form because he is a lesser version, as he seemed superior to madara. it must be unique because of other reasons. so he may actually still look different, but with a similar type of wardrobe change.
Will he have his own version of the 10 tails "form" like madara? the staff the grey hair and chakra robe
