Would this be LA overkill?

Would this be too much? I’m thinking of using the ORIGINAL edition of LLATL and also Climbing to Good English at half pace. My reasoning… The original LLATL lessons are short and to the point, perfect for a quick tutoring session with mama, despite the chaos from an active 18mo. It will provide copywork and dictation. CtGE we will do behind grade level, and slowly, just a half page per day. I want it to be some independent practice of writing and spelling, and also something they can get started on even when I’m busy with the younger kids. LLATL provides examples of good writing for them to copy, CGE provides some explicit instruction on how to summarize, outline, write a letter, etc… My 8yo 2nd grader will finish up book 1, my 10yo 4th grader will finish up book 2 (they started these books this year, completed less than half). why not just use the newer LLATL? Because the bouncing all over, covering so many different things each day annoys me. And it’s a few minutes with teacher, then a few independent, then back to the teacher, etc. That just won’t work well for me. Yes, I could split them up myself, but I think this way will be easier. No weeding through the material. Plus my kids will have clear and consistent expectations of what they have to do. Always the same, and they won’t have to wait for me to tell them what and which pages to do. How does this sound? We will technically be doing two complete English programs. But LLATL is known for being ‘light’ (and I’m using the older, lighter version too) and I will be using CGE behind and half pace. Would adding a HWOT workbook to this be too much? I wouldn’t add it, except this coming year my kids need some cursive instruction.
