Adding weight for that would decrease range, maneuverability, speed, and payload capacity. At the same time, you'd need much more precision to enter through the created hole. While suffering from reduced maneuverability. So this seems rather impractical. Mine-laying drones would make more sense to me.

Same with the ,,cope cages" everyone was joking about in the early years of the war.

If it works it ain't stupid, even if it looks ridiculous at first glance.
