Also (and this demonstrates my lack of Pic line operational
knowledge), is it worth getting a Rayners Lane train and changing at
Acton Town?

On the basis that "a train in the platform is worth two on the departure
board" it is *always* worth getting one as far as you can, then
changing, if you are at all time-constrained on the journey.

For all you know, just after you've passed Hammersmith someone will jump
onto the lines there, and then your only hope of getting to LHR for the
next couple of hours will be an ad-hoc shuttle service from Acton Town.
