Extracting FX and using them in .world files

Hello! I hope this is in the right place but I was wondering if it's possible to extract a world effect and import it into a .world file? I'm not even sure if I'm using the correct wording for all of this, but basically, I'm interested in extracting the aurora-like effect from from the magical realm or the actual aurora from eco living and applying them to different worlds. I'm pretty familiar with changing world lighting, but I'm unsure of how I'd go about something like this so any help would be super appreciated. Thanks!
