I'd be cautious about a composite column here. I've found they can do some very sad things for performance, when you get enough titles in the library. I had a library of tens of thousands that included several date fields. I created composite columns to format the dates as YYYY.MM.DD to make them more navigable, and performance absolutely tanked.
This might be solved in newer calibre, but I haven't tried this in a couple years.
