I figured the base idea with just the minigun sounded straightforward enough. The more ambitious ideas, in order of expected difficulty... 1. Gatling laser variant. Vertibird Gatling Laser did something like this for the vertibird mounts, but the model was off for some reason. 2. Gauss and plasma variants. Simply changing the projectile type and muzzle flash would work, but maybe even making new models of weapons using vanilla assets? Use the receiver portion of the minigun but change the front to gauss/plasma barrels, like Any Mod Any Weapon? 3. Portability? Admittedly, not practical at all, since all these weapons are already portable anyway. But imagine if its combined with a mod that heavily tweaks recoil for heavy weapons, making firing it out of power armour uncontrollable. 4. Hostile NPC use of mounted weapons in their spawns. Presumably, this would entail actually going to each raider/gunner/BoS camp to specifically add it in, probably to replace turrets? Seems like a lot of work, not to mention taking some usefulness out of the turret hacking perk. 5. Hostile NPC use of PORTABLE mounted weapons. With (almost) no experience in modding, I'd imagine that this would be heavily AI script intensive. I dunno, could be talking out of my ass here.
