With no District Line, my usual route of Balham to Victoria on
Southern and District Line to HSK is a no-no. I was thinking of
going to Green Park (via Northern and Victoria lines) and getting a
no. 9 bus. Any other thoughts?

Balham to Clapham Junction, then Silverlink to West Brompton, District
to High St Ken, but the Silverlink service is only every half-hour.

The TfL Journey Planner gives various routes according to the precise
departure time, including the one you suggested.
