When you mention that, it makes me think that it wouldn't go well to implement. Think about the aspect of how Bungie has introduced cosmetic items, and we can either grind it or pay for it. If they do put something like that in, I see it going towards the line of being mostly silver based, since it has a relation to cosmetics, and also added to the pool of rewards. I think a more constructive and positive way to get this, is to recommend a way to turn rare guns and armor to legendary status so they can be infused. It would give a new meaning to customization. Be your own Guardian lol.
