Nope. I don't think.
Superman is known all around the world by the movies.
Superman is iconic by himself. Marvel's Thor is just a remake of a much more know real god. And the real god is different and has more charisma (it's an heroic moron).
Think to Spiderman. He's iconic by himself.
Thor is an "northen" figure. Marvel is an hyper-patriotic company (yes, we have another word for that...). Humans >>> non-humans ; USA-peoples >>> Other humans ; Anglo-saxons >>> Latins.
Thor is so powerful because is a germanic god. In Marvel, Asgardians >>> Other gods.
Anglo-saxons know well Thor.
In France, for example, Thor is a secondary god. Greecs, Romans and Egyptians are far more importance. The "Thor" character has not in France the same importance than in anglo-saxon and germanic countries. A character called "Thor" has to be strongly introduced in no-anglo-saxon countries, because he's not in the local culture.
Superman is not see as an "USA hero".
No matter who can adapt Superman.
Thor and remains a purely US character, who is interested really only in the USA. And it is still worse if you thinks of Avengers.
Peoples who don't know or like US comics (or even comics) can easily understand Superman : It's a good and gentle reporter who can change himself in godlike character who can fly, lift cars, shoot laser by his eyes and can't be harmed by bullets.
But Thor ? Who he is ? Thor is just a "uber-wank" as Wolverine, Hulk or Thanos.
Think to Spiderman : Easy to understand.
Superman is gentle, polite, humble. Superman is FRIENDLY. Superman is our friend. We can love Superman because you know he love you already.
Thor ? Err...
Think to Spiderman : He's gentle, polite, humble. Spiderman is Friendly. And funny.
What have Thor ? Just his uber-powa.
