Animated Armor/Weapon/Vehicle Coatings?

We’ve seen a large collection of weapon and vehicle coatings from MCC and even Infinite so far. What are your thoughts on possibly having animated coatings much like we have animated nameplates/emblems? Imagine an AR with fiery cracks all over, or a Commando pulsing with promethean energy, Or even reactive ones like a camo Coating that changes based on what map you’re on!
What’re your thoughts on this? Maybe have these special ones locked behind achievements? Got any ideas for it?
