At Jeff Ostrowski's suggestion, I'm posting this for general use. Bruce E. Ford adapted the Gloria VIII to English, and I've harmonized it. You can find it here: http://www.ccwatershed.org/media/pdfs/11/12/13/09-35-24_0.pdf
Hope you find this helpful - I'm using it at my parish because it has repeated motifs, which has made it a lot easier for the parishioners (who are NOT well-versed in chant or Latin!) to learn. They picked it up in about a month.
Perhaps you could eventually do a harmonization for the magnificat in the 8 modes, according to both 1973 translation and 1662 anglican book of common prayer translation (which is more accurate).
