Few things you may need to bear in mind about this:
-NPCs will no longer be able to scan for cargo. This mechanism is what's used to make them follow you, so regular scanning can't exist simultaneously with this.
-Each and every system where they spawn will have to have patrol paths inputted, as they only work off patrol paths. This is because regular area spawns don't scan you, whereas patrols do. This will likely cause a number of crashed and bugs and the like until it's perfect, as patrols are notoriously evil to make.
-Unless you can spawn the NPCs via Hook, which it seems you're working on, as the number of players increases the number of spawns will decrease as it does normally, and so people will be unable to use their wings.
-NPC wings won't follow you through systems, or in and out of bases, but will work through tradelanes.
