Well obviously, this should have some limitations, e.g. only be able to use stuff lootable from wrecks in your own ZoI? Perhaps have very,VERY good reasons for having certain weapons on? Besides, should you see a Corsair Titan with Buckshots on it, I doubt the player would have much time to enjoy the guns due to the 900 BHG on his tail collecting a hefty bounty on his head, right?
Also, for a Gaian with Black Widows, how useful do you REALLY think this would be? It's not like the Widows are any more deadly than Angels in the right hands.
Sucks to be a weight on the wrong side of the brilliance-insanity scale.
