Mythic weapon idea for hero's that unlikely to get weapon skin cause of their weapon design

Got this idea for a mythic weapon for Moria who likely will not get a weapon skin because her hero weapon design.

Her mythic weapon should be a magical book that she opens in one of the pages to suck peoples souls and another page to heal her teammates and her weapon flourish animations should be scrolling thru the book showing cool pictures of her magical ideas or experiments on other hero's where she shows how would she want to change them or experiment on them, and some flourishes might show the souls stuck on the book projected by 3rd animation.

i think this idea will solve her weapon mythic issue cause of her weapon design, there are other hero's that suffer the same issue because of their hero weapon design that might not get a weapon skin like Echo for example where her weapon is literally her arm.
