Conversion of armor & helm into vanity

I love these rare and epic armor and helm from the new expansion. I know they're recolored items, but Night Assassin has a great basic design to begin with and looks really stunning in white and red.

Any chance we might have some means to convert these kinds of beauties into vanity? Converting them to vanities will mean that players of any level can wear these items, there is less chance of them being flushed out in auto cleanups, and we can combine them with other gear with specific effects. The red assassin set will, I think, look nice with Antignome ground effect and the white one with Glintstone ground effect. But of course we can't don the full set for the ground effect while wearing these.

In light of their rarity, maybe the conversion can be effected by farmable tokens/crafting components instead of taking the the expensive way that costs arcane shard?

I'd love to be able to convert the gold demonlord rogue set into vanity set too.

Ah, what a killjoy.
