Magnificat - Adapted Lyrics

I have been toying with the idea of doing a musical arrangement of Mary's song, the Magnificat. I think I have the melody worked out. The lyrics that work with the rhythm will probably go like this:

My soul magnifies the Lord
My spirit rejoices in my Savior
   In my lowly state
   As I walk His ways
He remembered me
His eye turns towards the meek
His favor rests upon the humble
  He tells the proud to go
  He casts the ruler low
He remembered me

I'm still working to see if Elizabeth's response will fit in naturally as well. I picture it fitting in with some version of the O! Antiphons to round it out. We'll see. Wish me luck.
