How about using both of the rings in a crafting recipe to make them into a necklace, say maybe using Nates dog tag chain (Cause lets face it, those of us that were in the military never feel comfortable without our dog tags). The mod could add a pair of dog tags (like the brotherhood of steel tags, just not named as such) along with both rings that grants the stats from both rings. Lose the rings and the dog tags, get the combined necklace.
