Just recently, after the episode that read, "if Peggy Carter is Captain instead of Steve Rogers," the content of an What If episode? has been revealed: What if Steve Rogers becomes Iron Man instead of Captain America?
So let's find out what If story? This is in the comic.

If Peggy becomes Captain America?
The context of this film is probably based on the fictional film "Bullet Points" by writer J. Michael Straczynski. In the context of World War II, the United States needed super soldiers to be able to win this war. However, Dr. Erskine - who was responsible for the project "Rebirth" was assassinated by a German spy who shot and killed. He also killed Ben Parker - now a soldier escorting Dr. Erskine during the escape.
This caused the "Rebirth" project to be canceled by the US government, paving the way for the "Iron Man" project. Steve Rogers was involved in this project and became America's first Iron Man.

Iron Man helped the US war with the Allies win. Despite climbing to the rank of Colonel, however, this Iron Man armor has caused a lot of problems for Steve's health, both physically and mentally.

Meanwhile, Peter Parker living and growing up without the guidance of Uncle Ben should become a troublemaker. On a school trip, he sneaked into a test field in the middle of the desert. And that day, instead of Bruce Banner, Peter Parker chose the explosion from the Gamma bomb experiment and became the Hulk.

Peter Parker transformed into Hulk
After once losing control when transforming, Peter had to say goodbye to Aunt May before leaving. However, Steve has come to advise him, deciding to put on the armor despite retirement. Peter refused to follow Iron Man and turn into the Hulk, frantically beating Steve Rogers.

Shortly thereafter, a chain of events happened. The ship carrying the Fantastic Four during their fateful trip had trouble right after taking off. This brings it back to Earth. All members were involved in an accident after the crash except Reed Richards. Though lucky to survive, he lost a left eye.
Reed was later invited to lead S.H.I.E.L.D. From there, he devoted all his intelligence to turning S.HIELD into the world's leading counterterrorism organization. He recruited top experts in every field and promised to give them anything they wanted in return for their dedication to S.H.I.E.L.D.

Reed Richards - director of S.H.I.E.L.D.
Bruce Banner in this universe thought that Peter's accident was his fault, so he tested the spider collected from the test site. But being bitten by it made Bruce become a semi-spiderman creature fleeing everywhere. Bruce becomes Spider-Mankhi S.H.I.E.L.D. Take him home and create a suit to control Bruce's instability.

And then, Galactus along with his messenger Silver Surfer came to eat the Earth. In this universe, we do not have the Fantastic Four as in the original universe, so Reed's job is to call all superheroes / evil people around the world to join forces to fight Galactus.
Of course all efforts are in vain. But during the fight, Silver Surfer realized the fighting spirit of Peter - Hulk, that he did not fight for this world or money fame, ...
And you just want to protect your last relative - Aunt May only. Seeing that, Norrin created a reaction that made Galactus angrily go and find other planets less annoying.
