The
problem is the Southbound direction because the trains enter the
station from their source and then branch after.

If the branching could happen first that would resolve the problem. The
other option would be to have one wide platform between them, and yes
that would be further South where they are closer together.

The junctions start immediately south of the present platforms, and are
quite long. It's basically not possible without adding brand new tunnels
somewhere (probably from Chalk Farm / South Kentish Town to the opposite
southbound platform).
