I think it would be cool if not only could we infuse light, but we could infuse perks. Imagine... You are dismantling the weapon, so you could take the perk you want and replace an existing perk with it. It would have to be the same perk slot, and you could only do it once per slot, then that slot gets locked. You can infuse perks until all perk slots are locked. It should be very expensive, costing much glimmer, materials, parts and maybe one of those glass needles. You could create the perfect weapon for your play style.
