RAIL says a shuttle from Brentford's Golden Mile to Southall Station is
being seriously considered.

Do you have an online link? It's been considered at various times in recent years. I wrote a preliminary report on it for Hounslow in 2007.

Personally I think Brentford - Ealing
Hospital - Hanwell - Greenford - South Ruislip makes more sense, but
would obviously cost more, however I don't think any demolition would be
required. It would mean the nice new shuttle platform they put in at
West Ealing would become disused though.

How do you propose to get from Ealing Hospital (presumably a new station on the existing branch) to Hanwell? That would involve crossing over or under the GWML if you then want to run down the Greenford branch.
