Is there a way to Import a SEN simulation in either Rise 360 or Storyline 360

Both Rise and Storyline are authoring tools. Thus a published Scorm output you cannot import into either of them to edit. You can add the output ( Scorm or HTML ) into a WebObject and add that to either Rise or Storyline. Ofcourse you will not have options to edit it then.

For that you need to recreate the content and simulation in an authoring tool.
