The only one who might possibly survive is probably Queen Louise's third son, Lucien—that is, Prince Xiyaldo's brother.
Lucien is the offspring born to Queen Louise after she was resurrected by the Red Chancellor as the Son of the Moon. Undoubtedly, his relationship with the Red Chancellor would be much closer... If the Red Chancellor wishes to declare himself as a monarch, then even Lucien would not likely survive.
But there's another possibility, that the Red Chancellor would not take a public stand.
After all, with the fierce character of the Son of the Moon, they are not suited to be a monarch. Or rather, if the Son of the Moon became monarch, he would inevitably be a tyrant... That is an influence from both the Pillar Gods and Celestial Marshals, and not something that could be countered by mere rationality and will.
—After all, this was how the rule in the Narcissus Duchy collapsed.
