Hi JenniferHealy I have not done this, but provided your Storyline course is published to SCORM, you will not have a problem with completion based on the usual pre-requisites such as view all slides, complete a quiz or a trigger.
What you should be aware of, is any Rise courses bundled into Storyline will not track using SCORM as they would conflict with the Storyline course, and so they should only be included as Web HTML publish.
Also, I would question why Rise courses (full responsive and optimised for all device sizes) would be displayed within the context of Storyline (not responsive, and not a good experience for mobile users).
You would loose a lot of the benefits of Rise and it might be confusing to see a Rise module embedded in a Storyline course. I would advise against this.
It would be interesting to hear what you are looking to achieve as there may be other options such as SCORM content aggregation, that allows you to bundle multiple courses into a single offering with multiple tracked courses. You would need to confirm compatibility with your LMS though.
