Is there a mod that changes the animation of Kha-Beleth?

There's a mod for walking animations for the Lord in Zakhar's group that's been around for ages; if you're interested, I can provide a link.

That would be great. Especially if the mod only changes the graphics of that hero. Otherwise, digging through NHF for just one hero, even for personal use, isn't very appealing. Especially when it comes to the binary model files. And I'm saying this as an advanced user; for those who just want a plug-and-play solution, it's even more difficult. It's a dark forest...
