I'd say both can work; you can have Earth-63 be a alternate Earth that's basically Earth-3 + Earth-11 + Inverted Personality & Powers/Weaknesses, that way you can just explore what the Earth-63 characters get up too on their own time as well as what Earth-63 is like in general, while you can also do the whole "Imagimary Stories" thing with greentexts when you want to focus on that.
