[WH40K]Could an extremely powerful Librarian assume the duties of the Emperor for any length of time?

Given that the Librarians are super-human and kinda sorta descendants of the Emperor, could an extremely potent one cover for the Emperor for any period of time? Say a few days or weeks, or at least hours?

Malcador the Sigillite, The second most powerful psyker ever known could only inherit the Golden Throne for a small duration. Namely, the time the Emperor, blessed be his name, battled and killed the Arc-Heretic Horus.

After the duration he was reduced to nothing but dust, even for a man of Malcador's strength, the stress was too much.

Technically, you could have a Librarian success the Emperor on the Golden Throne, but the time is going to be short. As there probably is no Librarian who can meet up to Malcador the Sigillite's strength.
