[Marvel] How would the Marvel universe differ if Tony Stark's and Bruce Banner's roles had been reversed?

Say the Marvel universe was the same up until that point where Tony Stark was struck by a gamma bomb and Bruce Banner was kidnapped by terrorists. What's the outcome?

Tony Stark, while working on a military project, is wounded by a gamma-radiation land mine and rushed back to the States. He finds his intelligence vastly increased, Leader-style, but the StarkTech weapon was a little *too* well-designed. He is fatally and irreversibly irradiated.

Desperate, he builds a suit to support his failing body and contain the radiation. But the prototype is faulty and his secretary Pepper and driver Happy are given lethal doses of radiation. They die, despite all of Tony's efforts. In a rage, he permanently seals himself inside a massively oversized suit, the **Iron Hulk**. He is now a chaotic force for good.

Bruce Banner is kidnapped by terrorists and forced to build a gamma bomb. But Bruce is not a weapons designer and sabotages his own work. It explodes prematurely, embedding shrapnel in his heart and brain. The radiation enhances his intelligence. It also enhances his strength She-Hulk style, but not to grotesque proportions.

Banner is trapped in this new form. He can't ever grow too big, or the shrapnel will kill him. Same deal if he turns back to normal. He must maintain a calm and rational emotional state in order to stay alive. He trains with Doctor Strange, who teaches him the way of inner peace. When he comes down from the mountain he takes a new name, **Professor Incredible**. Scientist, adventurer, and unstoppable lady's man.
