There are a bunch of these already, so I must say that such an "answer" now seems about 40 years late.
In any case, I am no one to speak, as I'm working on a Rite I version of my Breviary which puts Noonday and Compline into traditional language, uses the 1928 Psalter, and has versions of the Rite 2-only Canticles adapted from the Great Bible.
This sounds exquisite and perhaps you might let us incorporate it into our project. The Noonday Prayer and the Canticles specifically would be of great use as we have no traditional source for these; we do have sources for Prime, Matins, Evensong and Compline; we are taking these from the 1928 Deposited Book. The Canticles would be very nice, taken from the Great Bible, as our plan all along has been to put Phos Hilarion in Evensong with a rubric requiring it or the alternative Psalm be sung in place of the Magnificat, with the Magnificat or the alternative psalm replacing the Nunc Dimitis, if Compline is to be served later, thus allowing for the restoration of the traditional use of the Magnificat at Vespers and Nunc Dimitis at Compline common to most forms of the Western Rite (the Phos Hilarion on the other hand is, as I am certain ypu know, but other members might not realize, from the Byzantine Rite of the Eastern churches).
Thus, it will be possible for a parish to divide Choral Evensong into Vespers and Compline, if desired. I like to think of the actual text as Evening Prayer as a service that is essentislly of a vesperal nature, that could be used either for Vespers exclusively, or also, as Cranmer intended, and as is often the case, as a replacement for Compline as well. But I do believe we ought to use Choral Evensong to refer to the combination of Vespers and Compline in the Office of Evening Prayer, and thus we can refer to the various settings of it, like the famed Gloucester Service or St. Augustine's Service or Chichester Service or other settings of Evensong by Herbert Howells, whereas when Evening Prayer is served followed by Compline, we should call it Vespers, and ensure it begins ideally with Phos Hilarion in the Eastern tradition, and ends with the Magnificat, and that Compline uniquely is enriched by.
Morning Prayer in turn is of course a combination of Matins, Lauds and Prime, but in traditional High Church Anglican usage, I have quite often found that Prime is more frequently said before it, as a sunrise service, and Morning Prayer is said before the Litany and Holy Communion. If a parish or cathedral also has said services and multiple chapels this can all get quite complex.
I don't know what the Order of the Holy Cross or our other beleaguered monastics do right now, but a proper monastic usage using, say, the 1928 American BCP or the structurally very similiar 1928 Deposited Book of the Church of England, would be to use Morning Prayer or Mattins as the replacement for a midnight office, perhaps followed by a said service of communion, and then in the morning, serve Prime, the Litany and a Choral Eucharist, for the benefit of pilgrims, day visitors and people using the abbey as their parish church.
Cranmer alas never provided us with a satisfactory office of midday prayer, and the High Churchmen who gave us the 1928 American and English books were not Anglo Catholic enough to try. Only the 1962 Canadian Book of Prayer made an effort at this, but it is exceedingly brief; too short I think.
That, and the traditional language adaptation of Midday Prayer the 1979 American book in the Anglican Service Book (1990), are the only such services in traditional language, and to be blunt the version in the Anglican Service Book is much preferrable to the Canadian version or the modern language service from whence it was derived; unfortunately, it is not in the public domain.
So perhaps you could PM me a link to your version or we might exchange e-mails; if you did grant us permission to use your settings in our book we would give you full credit, and indeed I think we would love to do that as your name would I have no doubt add a certain
gravitas to our work, which will itself be released into the public domain.
