At least I'm not decomposing.
I haven't done arranging in quite awhile, but I had thought about rearranging some choral pieces for sax ensemble -- I used to work for a variety of churches and some of the Glad and Integrity Music acapella charts lend themselves nicely to sax partage: I did a complete arrangement of Glad's "O! For a Thousand Tongues to Sing" before relocating to a different church job where there just wasn't enough saxophone players (to do it "right", you need six; four can work, tho).
