and then a bus from Feltham
Clapham Junction now has lifts to all platforms - as does Feltham to cross the bridge for the bus. The buses are all low-floor types and generally have plenty space for luggage in the wheelchair/pushchair area (assuming neither of the above are on board!)
This is exactly what I would recommend as well.
