Adding Death Animation to a Custom Model

I'm using Callahan's Boss Omega model in my map, but I discovered that it doesn't have a death animation. Currently all of its animations are basically the same as an Infernal, so is anyone able to add on this death animation please? I've messaged Callahan, but thus far, I haven't had much success with people responding to private messages, so I'm not sure if I'll have any success in that route.

Here is a link to his model thread. The Boss Omega is the big purple/black Infernal type thing.

How does that sound like to you? To me it sounds like I should smite someone right now. But I won't 'cause I'm in a good mood. What I am going to do though is to close down this thread, because you can't just edit someone's model like that without the author's permission. If he didn't answer you, tough luck, means you'll have to start searching for another model for your map or fake its death via triggers or something.
