It's difficult to work out what would be the best option
if they did decide to rebuild - perhaps a sub-surface
ticket hall immediately to the north of the market
buildings, with several surface entrances
(similar to Leicester Square). Escalators would
then lead down in a northerly direction to a long
concourse parallel but above and to the south
of the platform tunnels. From there perhaps
three or four new passageways and staircases
down to the platforms, as well as
incorporating the existing two staircases.

Wheelchair access would be legally required.

That's fairly easy - the wheelchair access would be via a new lift
installed in place of the existing ones (on which site would also
presumably be the existing emergency stair exit).
