Can this be somehow used in a Vanilla Wordpress Site ? or could some Plugin be made and use this in WP?
Yes — it is possible to insert ready animation in WordPress, here as it to make examples: 1) http://old.edgedocks.com/content/video-edge-animate-and-cms-wordpress-0 2) http://old.edgedocks.com/content/edge-suite-integrate-edge-animate-wordpress
Plugin: https://wordpress.org/plugins/edge-suite/ (I recommend strongly to read the description to a plug-in)
It is also necessary to understand that it is necessary to edit animation (to change parameters) adobe edge animate
