I'm not sure I follow. The tracks don't converge until a considerable
distance east, and in fact they go under Harrow Road bridge through
completely separate spans. I think you'd even be able to take the
siding through one of those spans, which would get you 8 car platforms
and an 8 car centre siding.

It all depends where they put the pointwork.
