That's a creative idea, but it's not that simple. You can't remodel the shape of mobs, not to mention that blazes have more than a few too many limbs.
I'll be releasing a download link as soon as I'm done with all of the 2015 structures. That means all of the shrines, the ancient city, the ruins in the ice region, and at least a couple huts per region. Oh! And the temple of time as well.(I still need to figure out where that is)
I'm nearly finished with the city, I have half of the shrines done, and I still have to do the rest. If I were to guess, I'd probably say that the first release will be out in November, but no promises.
That's totally doable, I just would rather have him be an actual enemy than a statue. Furthermore, the armor stands will only be able to hold swords in their right hands.
I can make him in 1.9 as a fully fledged enemy for sure, but unfortunately that's not out yet as a full release and I need world edit to do my building. He and Basher will be around someday, just not right now.
