How about killing the Chiltern services to everywhere inward of Denham
(or perhaps West Ruislip, for interchange), so that the services left
can run fast all the way into Marylebone, and then speeding up the
Central Line's services from these outer stations by taking over the
GW Perivale line run some trains fast, say from Greenford to East
Acton (via new links at both stations), possibly with a stop at Park
Royal. Essentially, you have the Central running inner suburban and
'middle suburban' services.

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.
