Defias Mask Rogue Transmog

Please make this a transmog option somehow! I just recently logged on my twink rogue I had made like 8+ years ago and he looks DOPEEEE with his defias mask that I had to invade on Alliance territory to get. I still remember it well and I’m deeply disappointed it is not a transmog option that I can use to change my heirloom set. I believe it’s because it’s grey, if you simply changed it to white I believe I could transmog it. Please Blizzard, you’re my only hope.
