Hi, I am not asking someone to make me a theme from scratch, but can someone modify a theme for me?

Can someone turn the Montisart's Halo 2 theme into a more green and brown and parchment theme? Like Lord Of The Rings?

The theme is downloadable here >

And these are some sites that I want you to use colour skemes from >
