Also the track & platform layout is a mess - it's not possible to have a
through service switching between lines that stops at Gospel Oak.

Expect if through services off Goblin towards WJ ever happen (and it is in
one of the proposals), the bay will be closed and at least one platform
moved onto the westbound through line, possibly platforms on both lines...

Is it viable to make the through NLL platforms the reversing point for
GOBLIN trains? Whilst I can see a through service happening, I'd be
sceptical if it were for all services.

And do the track connections actually allow the GOBLIN to switch to the NLL
east of the platforms? My recollection is that they don't physically connect
at all on that side.
