"I have imagined the void balloon being much smaller, then using a
large number of them -"

Some time ago a Japanese neutrino detector was lined with
photomultipliers the size of a TV CRT.

One broke and the cascading shock wave broke a substantial fraction of the rest.

Not saying this would happen with a bunch of void balloons, but it is
something to consider.

If a few of these voxels are damaged, there are still plenty of others to mitigate a singular catastrophic implosion... you just lose buoyancy until you are parked.  :)  I guess having an unstable airship docking with your house would still be a bad day, but maybe not level the neighborhood.
