The need in the choirs is to have separate S, A, T, B and for those voices to be benchmarked using the Bach chorales, some Palestrina and Carmina Burana. This would cover a variety of styles for straight choral writing.
Following the VSL Strings approach, I'd like to see a full choir (say 8 voices per section or better) and then a chamber choir (smaller), and then soloists.
It would also be sensational to have a children's choir recorded, too.
Excellent point! We often think too much, especially for films in terms of Carmina Burana type choir. I must say, from one of the libraries i had, i used "solo boy" voice as part of a theme in a film, and it sounded so real and gave the chills every time you heard it! (But too bad it was the ONLY voice in the entire library that sounded real). Children choir? Absolutely!
