tradeable face and name card idea

hello, sts!

Recently my friend just got an idea to since we got tradeable stash, inventory, auction slots what about similar things, example "name changing card" or "face changing card" what we could use some in some way.

for free to play players it would be beneficial and the ones who spend regually in game and buy platinum they could sell this cards

it would be added in token section and removed at a single time use

let me know in comments if this idea good or not
