Specific fic - role switches

[theskytraveller.livejournal.com]

Hi, I'm searching for a specific fic (series?) that I read on ao3. The most I remember is that the roles of the various avengers were switched, for example Natasha was Captain America, while Steve was the Black Widow(er?). Tony ended up being the only one able to lift Mjölnir and made the Iron Man armour for Thor. And Clint was an army volunteer for Bruce's project, which ended up with him turning into the Hulk and fleeing toghether with Bruce, who was quite good with bow and arrow.
