There's also the question of what to do with all the passenger
accommodation at Waterloo International, waiting rooms, immigration
offices, etc. Would it convert into a shopping mall? ;-)

Half of it is already shops.

Also, the routes through the terminal will have to be considered - while
getting on is relatively straight forward assuming they drop the
last-minute-only boarding scheme, getting off currently involves a
considerable walk through the bowels of the building.

Not necessary once you do away with customs, immigration and insecurity.
build a mezanine over the current sunken area before the barrier line and
have level access to the platforms as per the rest of the station.
