I like to weave character studies into history like this: http://wp.me/p48PJM-41. But if you want something with more structure, try characterconcepts.com. Boyer has several products, including Character Trails which would work for you. You can also buy from graceandtruthbooks here http://www.graceandtruthbooks.com/product/character-trails-learning-to-walk-in-paths-of-righteousness
On the more expensive side is the Keepers of the Faith Character series: http://www.keepersofthefaith.com/category/WriteUponMyHeartCharacterCurriculum. Haven't used this myself, but other products from them have been great.
