I'm sure you're right about demolishing the whole wall - this plan
gives 6.7 gates per platform, which to my mind will absorb most if not
all of the width of a single platfrom plus associated track.

On a related note, I thought a major redevelopment of Waterloo which
would lower the concourse and extend the platforms above it was on the
cards in the next couple of years. Although the gate hardware will be
re-usable, I'm sure there will be some significant costs around this
short-term deployment.
