I can understand that you do not want to support piracy. And with a great game like this I agree with you.
It really sucks that I had to register myself to Steam whilst I bought a physical version of this game. And I just don't want to use their modmanager.
So if anyone is willing to upload this for me or send me a PM with a download link I'd be very gratefull.
EDIT
This mod seems great though. I might just download it through Steam.. But rather not!
