Well, the death scenes needs to be updated, with the new details we have from the Yurofsky note (example, Olga and Tatyana in each other's arms, etc.), but being all blood and guts? I don't think so.
As for the Ipatievskaya Dom scenes, it would be difficult, because we don't know a lot about what happened to them in those days, and it was probably tedium and repetitive...I dunno.
