[Marvel] Asgardians seek to take over 'Midgard' (Earth), how does it end?

Do we end up with another Sam Lane from the DC Universe, as he was with Kryptonians? 

Or do we find a different path, an enslaved Earth perhaps?

Honestly, Asgard wouldn't stand a chance. Remember, Thor is exceptional among his people. That's why he's their champion after all; he's the biggest and raddest guy on the block. Second only to Odin, and with Loki bringing up a close third. However, he's been fought to a standstill by Earth heroes and villains before. He may be one of the strongest heroes on Earth, but he's not THE strongest. And he'd have to deal with all the big guns targeting him at the same time. Maybe he could take Hulk on his own. Maybe. But fighting Hulk while Prof. Xavier is mind raping him, Magneto is chucking skyscrapers and Spider-Man is making bad jokes? He couldn't handle it.

As for the rest, your Average Asgardian is about as powerful as a low level Earth Hero, but they lack a lot of the advantages that make Thor so mighty. Much of his strength, flight, and magic come from Mjolnir, which is a one of a kind relic. While there are other powerful weapons, your average Asgardian foot soldier is probably going to have just a sword or axe or something. Not even a gun. Even street level heroes like Daredevil aren't scared of tough guys with swords.

Asgard would also be facing all the various parties who, while not affiliated with Earth necessarily, still have a vested interest in protecting it, or just stopping a militant Asgard. Silver surfer, The Starjammers, the Guardians of the Galaxy, the Nova Corps. They'd all show up to put a stop to it. 

The one wild card is Odin, seeing as how his power is on a level outside of anything seen on Earth outside of, say, the Phoenix Force. But when that was a threat, Earth handled it. When Galactus rolled up looking hungry, Earth sent him packing. Unlimited power is not a guaranteed victory, especially if you are looking to conquer rather than destroy.
