Oh I'd definitely be into that too tbh. I had a starter a while back for an rp I was doing that kind of lead into something kind of like that where it started with Hamuko waking up fresh out of the grave. Kinda morbid but I'd like just read a bunch of Jason Todd Red Hood comics when I wrote it.
It'd be up for discussion definitely! Since the premise is that somehow they finally sorta perminantly saved the world, so Minato(or Hamuko) wouldn't need to be the seal.
