How much re-plumbing and tunnelling would be needed to have the

(I assume this would be done if they ever split the Northern Line into
two lines?)

Surely splitting the Northern Line would *remove* any benefits of
doing this? At the moment, each southbound platfrom sends trains down
either the Charing Cross, or the Bank branch. Were the line split, one
presumes that the Charing Cross branch would be permenently wed to one
of the Edgware and Barnet branches, and the Bank branch wedded to the
other one. The station would then automatically become one that
provided a cross-platform interchange between two north/south lines,
much like Finsbury Park. No tunnelling needed.
