We teach Arabic daily PreK-high school, and we would also like to use Daily 5/CAFE as an instructional format for that. Have you gotten your Chinese language teachers any Daily 5 PD? It is an awesome format for L2 as well, I think, but I'm sure many tweaks are necessary. We focus on oral language (perhaps a 70%/30% ratio speaking-listening vs reading-writing time-wise) in PK-5th grade, so that alone would require some changes. I don't have answers to your question, but would love to learn how you implement this and hope to share more ideas with you and other world language teachers!
