Pentakill Mortal Reminder: Behind the scenes?

Watching the "behind the scenes" video for Making of Xayah and Rakan was really enjoyable and fun. Now Mortal Reminder was outstanding ,very well made and was considerably a long video compared to most other videos.you think its possible that we get to see the process and behind the scenes of making it? i really want to see how it happened and how the animations and entire process worked.

Even if its not another video just a documentary with images and notes would be great.
