The mod "Wasteland Imports" has throwable weapon rocks that you can obtain from killing and looting Feral Ghouls. They are very nice. You're Welcome. https://www.nexusmods.com/fallout4/mods/3793/?
Vehicles will be very hard to make but if someone has the right attitude and mindset then I think it would be possible to make very immersive vehicles.
Awesome. I love Dead Money and think it was one of the greatest DLC I have ever played. I would love to have a Dead Money pack just like the Mojave Exports pack.
