Blackflame Covenant Armour Colour Synergy

I'm currently in endgame with my chaos witch and noticed there isn't really any chaos/purple armour. I've been running gloamgown anyway for ES recharge rate and that's the closest to something purple and witchy, but it got me thinking - wouldn't it be cool if fire themed armour had an alternate colour scheme if blackflame covenant was enabled?

Cloak of flame would look sick in a purple variant. And whilst the birth of fury boots are a bit chunky for a witch, the ability of running around causing chaos ignited ground is fun :)
