Olaf skin

It has been a long time since an Olaf skin has come out I just am wondering if one is being worked on would be nice or possibly a chroma for his ultimate skin would be nice. One cool skin idea that I though of would be kinda like the new teemo skin like possibly a special ops or green barret, it may be too much like the teemo skin though but would be cool he could throw machetes or something. I just think he needs some love in the skin department as most skins look pretty similar just change his clothes for the most part. Throw out some suggestion would be cool too hear them. Thanks
