MapleStory 2 Royal Hair/Face System Suggestion

Hey this might be a stupid suggestion, but would it be possible to consider adding a kind of chance system to the royal face/hair npc? Like I know it's random, but I tried to royal today and ended up using 30k nx on my face alone, and didn't not get the face I wanted, and I didn't even get to change my hair because I had used up all my nx. So, I was wondering if there was a way that you add a system where you can kinda be able to get the face you want, not so much a VIP system but, let me try to explain lol! So you know how in the royals 6 random faces you could get? What if we made a system where you could only get the same face only 2 times until you get through all the faces 2 times. Ugh I don't know how to explain this lmao! So like, lets use this week's faces as a example:

These are our choices this week:

Check out the Female Face Styles available now: Harin Face (NEW!), Sweet Cat (NEW!), Spring Fairy Face (NEW!), Starry Night Face, Adorable Girl Face, and Bulbous-Eyed Face.

~ SO let's say that I buy a coupon and use it and I get the, Harin Face. Not quite what I wanted, so I buy another coupon. I use that coupon and I get the, Bulbous-Eyed Face. Not what I wanted either, so I use another coupon and I get the, Harin Face AGAIN. So now that I've gotten the Harin Face 2 times I won't be able to get it again until I get all the faces twice, and the cycle repeats and repeats. ~

Does that make sense? I thought of this idea because like I said above, I spent 30k nx trying to get a face I really wanted and I kept getting the same faces. I got this one face like 3 or 4 times, it was ridiculous!
