Not really. Making Superman and Wonder Woman a couple brought new readers, but it also lost old – did it create a new ‘IP’? Or did it simply anger people because they didn’t want the respective company to screw them around? Superior Spider-Man was the same, did it bring new readers? It made a change to Marvel’s (truly) biggest character, was it ‘’well worth it’’? Nope. It doesn’t create attraction, creating an attraction needs real creativity, deciding to change Thor’s gender is a fad.
I think in the interest of the book and in the overall point of this discussion, that SM-WW was not designed with some great story in mind (or at least from what I can see from JL, SM and SM-WW.) It was created for the novelty of the relationship, something which a few Superman fans thought would be awesome. I didn't read anywhere in reference to this decision that Johns though that he had a great story in mind. In contrast to that though the new writer of Thor says that he does have a great story in mind. I am not sure why people would want something else. A writer evolves alongside their characters, and if this is the evolution of the writing, then so be it. Give it a chance.
Well as I said before, people will always say that something is impossible until it is proven otherwise. Those resisting female Thor are just literary luddites.
Not wanting a character, especially an all-time great character, unnecessarily altered/tampered with doesn't make one a literary luddite. It simply means one finds the existing character is fine the way he or she already is and doesn't want to, in a sense, 'lose' that character.
But you don't know that the character is lost, that is a knee jerk reaction which is impossible to know at this point. Whatever the writer has in mind, it has to involve more than "a female Thor". There has to be a lot of story behind it and I am sure that it will be good. A lot of such cases in comics have provided some of the best stories.
