Won't work. One of the fundamental principles is that A patent is a sword, not a shield. Owning a patent doesn't shield you from litigation, it simply allows you to litigate against others.

The "patent arsenal" idea is that if you have a trove of patents, you can respond to competitors by cross-licensing. The competitor won't sue you if they don't want to be sued in turn, a kind of mutual non-agression pact.

This doesn't work against a patent troll, who is not in business and cannot be sued on the basis of any patent. I apologize in advance if this simile is offensive, but I think patents are a little like nuclear weapons. They are very effective as a deterrent against other fully functioning countries attacking you, because they know that even if they "win" the war, they will lose.

But what is their value against terrorists? Nothing, because the terrorists do not have anything you can attack with a nuclear weapon. Worse, if you put a nuclear weapon in the hands of a criminal mastermind, you face extortion on a massive scale (see the movie "Thunderball").
