I agree with rotating or even streamlining the LA subjects. There is plenty of overlap there. WW would be an easy one with all the new voc. in the Sonlight books. And I'd drop the Geography workbook and do a small number of the Sonlight mapping activities pulling three separate subjects into one.
I agree with Peela. No one can do well day in and day out with an overwhelming schedule. Paring down a schedule where a student can excel is very often a blessing. Afwiw, I always have to cut my wish list and make our schedule a do-able one. Wish we could do it all, but you know.;) I'm sure you'll find the right fit with a little tweaking.
