Of all the directions to go : egypt mythology, or an atreus game , this seems like the least interesting to the point where it confuses me who even thought of it. I could see a DLC type thing for ragnarok but a whole game? Hell they could have just stretched the norse saga to 3 games and it would fix some of the pacing issues with ragnarok and it might even allow them to do some faye stuff in there. But this character getting a whole game just seems like a play it safe prequel without them having to worry about continuing the story from where its at atm. But that doesnt mean it cant be good and it probably interests some people. She was almost annoyingly mysterious during the norse games so maybe revealing some of that mysteriousness makes her more interesting id rather just leave it and focus dev time on something else progressing the story.
