I think for a project like this it would be well worth it. And besides that Alexander the Great is easily one of the most historically important people in the history of the world. At least top ten, and I don't see how adding a couple of birds to the background is going to set any ridiculous precedent. Look at the amazing helmet Bernie made, look at the amazing face/head Ekmek made. We're going all out on this one... at least we should.
I mean we are basically saying "Hey everyone, take out the regular Alexander and use this one." We have to give them a reason to do so, so in my mind the better and more unique the LH is the more likely people are to actually go through the trouble of using it. We might even want to make this one modular too, so its easier to install.
