But then we'd have to be able to have two (or more) work trees using
the same git directory, which current submodule code can't.

To me this sounds upside-down. I'd put the three sub-sites into
different repositories and the shared content into a submodule that
all three sub-sites use. At least that is how I do all my content
sharing on the websites I have done ... does that make sense?
