There are a number of additional verses and alternate choruses that have been penned by more recent singer/songwriters, including the following one, which is used by Alaskan singer/songwriter Libby Roderick:

"America, America, / God shed Her grace on me / and crown our good with humanhood / so we can all be free

I believe the above version appears on her first album, entitled "If you see a dream." While it may not suit your purposes, it's worth a listen.
