Thank you, Derek for your very useful link to past discussions about Rhetoric 1 through WTM academy. I spoke to Steve at WTM Academy and it seems that they have decided to change their literature courses to involve about 2/3 of what they did this year, to allow for deeper analysis and longer writing assignments. I've decided I like the combination, along with writing instruction from an instructor I will hire, separately. Combining the Rhetoric and Literature classes in the same year would be too much, in my opinion. I still don't have a good feel for how in depth the literary analysis is, for an advanced high schooler.
WTM Academy is going to offer an Honors level series of history classes that will include primary document analysis, for the 2016-2017 school year, I was told, if any one else is looking for history classes.
