You might play around with using those words in the verse version, tweaking them around to get them to scan.
That's another thing I occasionally do, write a prose version of a song, and then translate it into verse. Not very often, but it can help sometimes. Someone who often does this is an Essex songwriter called Tony Kendall.
Further back, the 17th Century poet and mystic Thomas Traherne used to do it - and his prose versions read better than then verse tyranlsations, which are pretty good.
