Editing a Rise course using a SCORM file from Cornerstone LMS

Hi - this is probably impossible, but I am going to ask anyway! LOL

My stakeholder has an old course they need updated that lives in our LMS (Cornerstone). The original course was built in Rise, but they have since lost access to the 360 account and thus, the original Rise course.

I was able to download the SCORM package from the LMS. Is there anyway to resurrect/edit this course in 360 using this SCORM package?
