Would it be possible for the Catechism of the Catholic Church Collection to get a refresh? (Logos.com link.)
It really is a pretty decent introductory collection, but it might be possible to improve it... and one improvement that I would suggest is having a version of it with the Libreria Editrice Vaticana's edition of the Catechism of the Catholic Church, for the sake of interested customers outside of the US and Canada.
