Keep in mind that Kensington Olympia's former up loop can easily be

useful when pathing the service.

Possible maybe, but it doesn't look easy to me. You'd have to
demolish the new platform and re-build the old one. What would you
do with the Southbound service while you were doing that?

Use the current platform while rebuilding the old platform to modern
standards over the necessary length, say 8 coaches?
A temporary, moveable flat bridge would be needed to access the currently
in use platform. Demolish half the current platform (you'd to retain a four
coach lengh for the current service) and provide the new running line in
front of the renewed old platform, as a short platform loop off the through
line. Then demolish the remaining current platform and extend the loop to
whatever length you want to allow for increase line speeds on entry/exit.

Alternatively, having completely rebuilt the old platform, demolish the
current platform and provide the full length loop in a 'big bang' closure of
a few weeks.

I also suspect that if they were to do it now, the weekday timetable could
be worked with one platform. Once the LO service frequency is doubled that
will probably no longer be possible.
