In my experience, trying to locate holes and align them, no. You
wouldn't b happy with the results. I'd say either drill from bottom,
right side up, or drill from top, top side down.
Problem with turning the board over is not the dust collection, it's
the large (and bulky) drill mechanism. Clamps are not always needed,
but might help. Hydraulics are not needed, but a spring and solenoid
might help.
It does sound like an interesting project.
