Confirmed: Hagoromo does have an incarnation

[A v i]

IMO It is Minato and Itachi.

Ha ha...Kaguya thought at first that Sasuke and Naruto are her two sons because of the similar chakra(hermit chakra of the six path's) and techniques. But she could figure out that's not the case and they are Ashura+Indora after all.
Hagoromo can't have a transmigrant because he exists still as a form of floating chakra.
