I have just realized that Tony Costa, in his book Worship and the Risen Jesus in the Pauline Letters (Peter Lang, 2013) incorporates the Pastorals in his analysis. He acknowledges the debate surrounding authorship, but announces at the outset that he will include all the letters attributed to Paul in his investigation. I have only been able to scan the book online, but it looks like the Pastorals show up fairly often.

I am encouraged to see this as we, in this space and in our ETS study group, are investigating how the typical neglect of the Pastorals impacts our view of Paul.
