Ive mentioned this a thousand time but it seems fitting here. Im not so much for Link "Dying" if we play as Zelda, let it be during the 7 year Link was Sealed away in OoT. It would be easy to build that story as OoT didnt really mention anything about what happen during the 7 years besides gannon gaining power and bringing darkness to the land, thats standard video game setting material there. so the prologue of the story could be You as Zelda, as gannon was deceiving his way through the castle to find Zelda. Impa figures out whats going on and she comes to get you, Que Player Controlled Into section, following Impa in your lil Dress learning the controls till you get to the horse and race out of the castle, Gannon following close behind. When you reach the gate to Hyrule Field a cut-scene reminiscent of OoTs scene where Link finds himself Face to Face with Gannon for the first time, and you ride off with Impa!
From there the New story would begin, where Zelda Ditches the dress and trains to become a Sheik! im guessing the main quest would be to set things in motion for the Awakening of Link, which would be the end goal. In my head i struggle with the story being much like OoT just to make sense; Like as a sheik you know who the Sages were and you could have a mission for every sage, im not good at creating gameplay situations but you could imagine, and you goal would end with the Sage heading off to do whatever they were doing before Link ran into them during your playthrough of the original OoT.
I getting carried away, long story short that is really the only way playing as zelda would make sense to me. I guess story could be different, if you want Link to die, then so be it, i just dont like it, but if i play as Zelda i want to be Sheik, not lil princess like zelda.
