I tried the phonics workbooks, too, but really did not care for them. I just got rid of them and kept the readers, and I don't think my kids are missing anything.
My K-3 kids do: SCM Copywork with some dictation, Pathway readers aloud or for oral narration, Rod and Staff spelling (b/c I just like for them to do these - they aren't CM). The older kids have brief writing assignments as well.
I do recommend the Rod and Staff Reading workbooks and Readers for older kids (3-6th). They aren't really CM, either, but I love the great stories and how they make the child 'dig' into vocabulary and comprehension a little bit.
In general, I think you should feel no guilt at all about throwing out the things that don't work for your children. If they hate something, they probably aren't learning from it and would benefit from a more 'living' method!
