This is one of those moments that propably everyone gets at some point of their life when they do something awesome, think it's the best ever, and then they see something like this which reminds them that no matter what, there will allways be someone, somewhere, who does what you do, but so much better that you just say to yourself: "Damn, that guy did it perfectly. He must be som sort of God..."
Thanks man, I totally know what you mean though. I'll probably be living in Harrison's/Volpins shadow for the rest of my life! Its just the way it is, and I just take it as a little motivation to do better, faster.
Blizzard used to have a contact for "official products" oportunities, but it grew into partnerships with other companies.
Sideshow Collectibles is Blizz's action figure partner. You could talk to them. [link]
Or you could start a non-profit Kickstarter fund [link] to create copies for whoever wants one. Each donor would buy a copy and will pay for logistics, etc. If you do want profit, you should talk to Blizz or Sideshow.
This is me being crazy, but crazy has worked in the past. Shoot me a pm if you do any of these.
