What if there was a completionist achieve

So with wotlk classic coming out soon, many of us are already hunting achievements and starting completionism. I have always thought this was one of the best ways to play the game, but there’s no reward for doing all these achieves (other than the over 9k FOS). But I was thinking, since we’re already seeing the UDE TCG items being repurposed in classic, maybe using them as rewards would be a cool idea for achieve hunters? Don’t make it easy though, of course. I’m curious to see what the community thinks about this idea, I don’t realistically expect blizzard to read this or consider it though.

My idea: (This is based off my memory, IIRC there was like 13.4k achieve points total in wotlk)

9k achieve points : choice of 1 tcg tabard
10k achieve points: a misc tcg item & second tabard choice
11k achieve points: rare misc item & 3rd tabard choice
12k achieve points: rare mount & 4th tabard
13k achieve points: spectral tiger?
Completion: UDE ogre idol & remaining tabards.
