I agree as well. From what you said make sense. Plus kokushibou use breath of the moon not breath of the sun. But I still think Kokushibou is relate to breath of the sun user perhaps they were brothers or Cousins.

If I have to guess when the man talk to sumiyoshi why he hate himself calling himself a man of no worth. Probably because he fail to kill Muzan and fail to protect people he care about.

Breath of the suns has no succesor but Kokushibou does. Its very likely they are brothers or cousins though.
