Could they just send lots of ships on the same path and specifically design them to break apart outward if destroyed, eg spin them at very high rates, to basically sweep the path clean, or would most of the particles in the path only be there because they happened to move into the path momentarily? I don’t know much about the velocities of interstellar particles.
