Is this possible

Hey guys, I absolutely love using your theme but was wondering if this would at all be possible. I really like waht they have done to the header here and was wondering if it is at all possible be copied over to this theme?

I just like the logo and how the menu will be placed etc so basically just the header and then the rest i would like to use this theme as a basis?

Hope it would be possible ?
