Why wouldn't the "filling" of that black hole shell be the pressure of the so-called dark energy that's inflating the universe itself? Maybe it's the leakage of these additional sources of dark energy that's fueling the increasing expansion of space-time. Armchair physics here, but it's fascinating to ponder.
