Yeps. Hagoromo and Hamura are half alien half human, Asura and Indra are 1/4 alien 3/4 human, already with no visible alien traits whatsoever, so Asura and Indra's children and their children were mostly Otsutsuki by name alone if anything, no wonder they changed it to Uchiha and Senju eventually. But I think Hamura's Moon descendants (last being Toneri) were more alien by blood than Asura and Indra even, probably by means of inbreeding the genes were preserved, unlike on Earth, where they have vanished almost completely, with the exception of Hyuga having their eyes.
