When I want to do anything "clever" with holes, I use a special variable
I then difference () all of my geometry called with $negative=false with
the same code called with $negative set true. With $negative false,
everything creates its "form", and with it true, creates its holes.
You can then smooth the positive form before removing sharp holes. I
find minkowski too slow and generally smooth things in other (non
trivial!) ways, but I can't immediately see how to apply these to your
case (pun intended!).
I generally use this approach when I want "holes" a module creates to be
removed from all other modules too, which happens naturally as all the
$negative false parts are (implicitly) unioned and then the union of the
negative true parts is removed.
Hope this helps.
