The A4 and Hammersmith gyratory blight the surrounding area so there is a certain attraction to sticking them underground and out of sight... but this would mean spending billions on car journeys into central London just so they can crawl along at a few mph.

I can't see it happening - the Chiswick NIMBYs will be out in force against the big fuck-off Crossrail-like construction that would be needed in W4.
There's another tunnel scheme being promoted here - put the A4 underground:
