However, I have a damn good rig so I have both the outdated Populated Wasteland and the REpopulated version. I also highly recommend REpopulated Wasteland, it's a updated version of Populated Wasteland but WITHOUT the military like the NCR and the Legion being modified or added in parts of the mojave.
And also, if you need ESP slots when you're running out of space for plugins, just merge the files that are related to the spawning of civilians, military, and town guards. Give it a shot and then determine if you still would like to keep it or not. However, it is very script heavy, and if you don't have a capable rig but I'm assuming you do cause you're listing all these different mods. It's called Increased Wasteland Spawns or IWS, I love the mod and I can't go without it in a playthrough. A few mods that you listed that I'm familiar with but there's one mod that adds NPCs ALL over the wasteland and can be modified with the MCM menu to turn your Mojave into a more populated area or a downright warzone in some areas.
