Produce Music

Hello, I have a song that is already arranged and produced. Title "My Garden of Eden" see attachment. I wouldn't say I like the country music guitar style that is at the intro. I don't like really the "Country music" feel that the guitar gives in the first 35 seconds and it comes back at the Bridge at 1:15. Can you replace it with a romantic/heartfelt Keys/piano. Like the attached file named "Example of Song". They didn't provide the tracks. Is it possible to fix this song for me? I don't have the separated stems. I was thinking that you could play the piano and try to remove the guitar or lower the guitar volume as it is played by itself.
