There are really tons of good alto/mezzosoprano repertoire (being one myself, I certainly could give you a very long list

), but I find that you are crossing out an awful lot already and are very specific about what it should and shouldn't be, which is of course very limiting.
1. It has to be English/translated - why if I may ask, because that somehow really narrows it down quite a bit and takes away some of the most beautiful pieces ever written. Is it a problem with foreign languages in general (something every singer really has to tackle sooner or later IMO), or does the setting or the audience require English language (especially the latter is really no necessity if a translation is provided in the program)? If no other language, what about Latin?
2. It shouldn't be 'the usual' Handel & Co. Is Purcell one of the usual suspects, too? If not, what about 'Vouchsafe, O Lord' (Te Deum)? But Purcell is probably not modern enough ...
3. It also has to have a certain standard - probably not too easy, neither too hard, both of which is very relative, since I don't kow your student. Grade 6/7 standard as such does not mean much (to me anyway) - if I look at the syllabus myself, there are pieces that IMO are by far harder than Grade 6 (Cherubino's aria for instance if you want to do it well), and other where I constantly ask myself why they don't appear in grade 3 or 4. Without knowing your student, I think we should at least take the grade off the list. Or maybe you could give us an idea what she normally sings well, and what she couldn't cope with at all. It at least would help with getting an idea about her voice structure.
4. It has to be sacred/oratorio - which I can understand if it has to be sung in some sort of church setting. If not however, I would suggest to have a look at easier operatic repertoire or song. You wrote it shouldn't be 'too operatic'. Again, it would help if you could describe why. Is it the setting, the voice etc?
Without more information, I feel the same as false_harmonic and cannot really pull more out of my hat than a few hymn settings or the Purcell at the moment ...
Crumbs! I'm doing my best here!
1. Really because we already have a lot of languages going on in other pieces so unlike normal, we could do with something in English. I guess Latin is OK, but again, we've done a lot of that.
2. I'm just trying to move a little bit away from things like 'O Rest in the Lord', 'O Thou that Tellest' etc. - if you like, the 'standard' alto/mezzo arias. I think we'd like something a little more modern really or something a bit difference - things people haven't heard done to death.
3. As I said, we've done things like 'O Rest in the Lord', 'Iris hence away' and suchlike. Ultimately, there probably should be many (if any) long semiquaver passages.
4. It doesn't have to be sacred - just fall into the oratorio/opera category.
More than anything, it's about finding new things - maybe things people don't hear all the time, or don't expect to hear?
