Inside a completion function, you can detect whether <TAB><TAB> was used
via the COMP_TYPE variable, so you could hack up a default completion
function that populates COMPREPLY with ls -ld output in such a case.
Something like:

_default_completion() {
    if (( COMP_TYPE == 63 )); then
        mapfile -t COMPREPLY < <(command ls -ld -- "$2"* 2>/dev/null)
    fi
}
complete -F _default_completion -o default -o bashdefault -D

This probably has several edge cases I've yet to think of, but I'm
pretty sure it will break bash-completion if you use that. I don't want
to dive into that mess though. Left as an exercise etc...
