Nancy Zieman from "Sewing with Nancy" always has patterns for jackets in her catalogs. Maybe try her website?

Another alternative would be to "quilt as you go" on lightweight yardage and then put a jacket pattern on that "quilted" fabric and cut and sew just as you would any other pattern. I've not done this, but it seems as if it would work.
Good luck with your project!
