Speculation aside, having been to New York the 4-track express/local
split works wonders - Manhattan is as a result far, far quicker to get
around than London, though the system has its own faults. It's a pity
London didn't go that way early on.

That said, I'm not sure you'd save a lot skip-stopping Barbican, which
is all you'd really manage. Perhaps a more effective way to speed up
the subsurface lines is for the stock to have acceleration/
deceleration like a Desiro and presumably a higher top speed to make
use of it. Will the S-stock manage that, or is the power supply not
up to it?

That said, if the infrastructure was there, a District Line that did
Earls Court-Victoria-Embankment-Blackfriars-Monument-Tower Gateway
would speed up that somewhat glacially slow service somewhat. The
western part, of course, already has express services in the form of
the Picc. A Central Line that missed out everything except the
interchanges would also be useful, same with the Picc, but I don't see
a lot of scope on other lines.
