Also the Gorosei obviously have an understanding that the three weapons exist. They even ordere Spandam to look for plutons blueprints. The WG could easily use the weapons to end the pirate era. If they had the ability to reach raftel they would have already.

Also i dont see Roger as an engineer. I realy daubt that he created something to counter attack the weapons.
