DMS Kakashi faired well against Kaguya, but she was caught off guard and had no idea he had those abilities. When she clearly knew that Naruto and Sasuke had been given power by Hagoromo, so saying DMS Kakashi > SPSM Naruto and Rinnegan Sasuke isn't accurate. Even if it was, both SPSM Naruto and Rinnegan Sasuke weren't even Hagoromo's level anyway. Sasuke didn't become Hagoromo's level until he combined the stolen TB powers with his Susanoo, and Naruto was able to match that after absorbing massive amounts of natural energy when he ran out of chakra from the other beasts.

If their level of power then was Hagoromo's level, and Hagoromo and Hamura together (back when Hamura only had Byakugan), were able to defeat and seal away the complete Ten-Tails. I'd assume that Hamura with his Tenseigan and the abilities that it grants him would be able to handle and defeat DMS Kakashi. Although it's hard to say, since we don't know Hamura's full capabilities.
