And how would the freight trains that use the Greenford loop and
the
ex-GW main line to get to the Chiltern route then do so?

The answer is to extend Crossrail (rather than Central line) services
to
West Ruislip via Northolt with a few via Drayton Park. Mixing
Crossrail
and freight should be less of a problem.

This would mean upgrading and electrifying the GW to West Ruislip.
West Ruislip is somewhat overserved anyway.

It would be better to spend the money electrifying the GW mainline
beyond Maidenhead.

I wouldn't disagree on the last point, but it would make a lot of sense to
extend some CrossRail services to High Wycombe instead of turning them
around outside Paddington. One or two of these per hour could run via
Ealing Broadway to replace the Greenford loop service.
