I'm pretty baffled that they've not been put in since? Is there any
reason why escalators couldn't replace the stairs? There are plenty of
places where they'd be a god-send.

I thought the stairs were deliberate for those who preferred for
whatever reason not to use escalators, and to make them easier to walk
up/down in the case of escalator failure (smaller steps with landings
compared with an escalator, generally). A set of stairs were
installed replacing one escalator at Liverpool Central for a similar
reason (in the early 1990s).
