Anyway, as has been pointed out, th W&C is tube gauge, not mainline, so
would need to be widened. Visionless naysayers protest that this would be
impossible, but i demur - that's exactly what, i read in CULG, was done to
the City & South London Railway when it became part of the Northern Line.
They even did much of the widening at night, with trains still running in
the day! Until they hit a gas main and exploded it, anyway.

Errrm, of course you don't actually need to widen the tunnel at all. You
hand over the new extended line to LUL and they run it with tube stock...
