I think it would be better if LU just closed a station completely for a
month
and did all the escalators there in one big lot rather than causing years
of
disruption.

At the smaller, less busy, stations, I'd agree. However, closures of
stations such as Liverpool Street, Victoria, Euston and Bank would affect
too many people and affect the stations adjacent too much.
