One Song, Two Ways

I just learned that a particularly "iconic" song, with lyrics written for Frank Sinatra in 1969, originated in 1967 as a popular French song that was acquired (i.e. bought) by an English-language lyricist. This lyricist transformed it into a song offering a sentiment that is the polar opposite of the original.

So, as is my habit, if I were to set this song as an instrumental piece without text (for personal non-commercial use only), can my setting combine the two "faces" of this song and still please the person interested in hearing it "her way?"

I offer a summary of the original text:

You don't wake up when I do. I cover you so that you won't be cold, get up, get dressed, drink my coffee, and quietly leave the house. As usual I am late. It's grey outside, and I'm cold, so I raise my collar. I will pretend during the day that everything is fine. You are not home when I return, so I go to bed alone, hiding my tears, while I wait for you. You will come home, and you will lie down. We will kiss, and make love, and we will pretend, as usual.

And here is a summary of the "rebranded" American lyric:

I have lived a full life, and during my many travels I planned everything carefully. I have only a very few regrets, and faced every challenge. I laugh at the things that I have lost, considering how much I have done. I have said what was on my mind, and did everything according to my rules.
