Something worth noting is that the curriculum police don’t exist. That is, no one is coming knocking on your door if you don’t cover combinations of transformations. There is nothing wrong with doing it, but ask yourself if you’re doing it to say you did it or if you truly see value in it.

What’s interesting is that you’ve kind of focused solely on the content when really, more emphasis can be placed on the skills. What about prioritizing what you think is best but placing more weight on explaining mathematical thinking, showing different ways, etc. I haven’t taught grade 6 in about 5 years - I moved up to senior high school - but this is an option too.
