[Marvel Comics] How different would Earth-616 be if a young Magneto had joined the Invaders?

In this scenario, assume that the classic Invaders (Captain America, Bucky, Human Torch, Toro, Namor) liberate Auschwitz in 1944 with the help of Erik Lensherr whose powers are developing. They convince him to join and aid their cause as Magneto, Master of Magnets.

1. In general, how does this shift history?

2. Magneto discovers that his teammate Namor is a fellow mutant. How does this change the way mutants are regarded by the rest of the world?

3. Alternate version: Magneto misses his chance to escape in 1944 during a revolt and instead is found by the Russians in 1945 when they finally liberate the camp. What changes for the USSR of they have Magneto on their side after the war?

1. There's a chance Magneto doesn't become a villain if he's developed as a hero alongside Captain America, and he sees that there are people who will go out of their way to defend those who are different than them.  Of course, Namor might convince Magneto of his superiority but probably not.  Magneto would make sure the Invaders went to free the other Concentration Camps, and he'd be an extraordinary asset - particularly with Cap and his shield.  He could have also saved Bucky from Zemo's rocket, preventing Cap from being super bummed when he was unfrozen and preventing the Winter Soldier from happening.

2. Magneto would publicize his and Namor's achievements in WW2 and they'd be regarded as heroes by the Allied propaganda machine.  Potentially leading to a deeply religious country declaring that mutants were gifts from god to defeat the Nazi menace.  Good early press lowers the amount of persecution they suffer later.

3. Magneto would probably treat Russia the same as he treats America in mainstream comics.  He would of course have to read communist works if he were brought into the USSR government, and the Communist Manifesto talks a lot about alienation from your labor and exploitation of the worker.  Magneto would see the USSR taking credit for his successes and then see that they're exploiting him for his mutant abilities.  He would then become a mutant supremacist terrorist in Russia.
