A tiny drone still needs the mass and reach to stop a missile

Could a few-kilogram drone be placed in the path of an approaching anti-ship missile as an interceptor?

Such a small drone may lack the destructive force, reach, and numbers needed to stop the missile far enough from the ship.

Simply occupying the missile's path does not guarantee a useful kill. The interceptor has to damage a fast and often heavy weapon decisively enough to prevent it reaching the ship. It must also arrive at the correct point with sufficient warning and preferably destroy the threat at a safe distance. Purpose-built interceptors carry substantial mass and explosive force, exposing the limits hidden by the very small drone concept.
