In fact, all it requires is Old Oak to be bypassed altogether, and
Chiltern trains to be given paths on the GW main line between
West Ealing and Acton Yard. The route from Acton Yard to
Clapham Junction already exists and is a regular freight route.
No new loop would be needed.

No, it would require a short curve in the vicinity of Acton Wells
Junction. (Admittedly levels might be an issue.) The curve from Acton
Wells Junction to the southbound WLL is already there, crossing the
canal twice, and not currently used by any passenger trains.

Those paths don't exist post-Crossrail. It's why the Greenford shuttle
was cut back to the new bay platform at West Ealing.

Chiltern wants to use its existing direct, fast, otherwise unused
route to dedicated platform(s) at OOC, not take a slow, congested
route, with flat junctions, shared with other GWR Relief line and WLL
services to CLJ.

This would provide a way of not only connecting to Crossrail, HS2, the
GWR and the WLL, but increasing Chiltern services without overloading
Marylebone.
