The 'tony is dusted instead of peter fanfiction' could have a very interesting plot. Since Tony is such a central and resource - rich character, his sudden dusting would be a huge shock. Pepper would be devastated. Peter, on the other hand, would be in a difficult position. He might try to use his own powers and intelligence to figure out a way to bring Tony back. The other Avengers would be looking to him for leadership in some ways, as he was the one closest to Tony among the younger heroes. And the whole dynamic of the post - 'dusted' world would be completely different from what we saw in the movies, with new alliances and strategies being formed in the absence of Tony.
It could also be that some of Thanos' followers or those who try to take advantage of the post - snap chaos become the main antagonists. For example, some of the rogue elements in the universe might see this as an opportunity to gain power and territory, and they would oppose the Avengers who are trying to restore order. So they could step up as the main threats in the fanfiction.
Well, one possible change could be that the Avengers' dynamic is severely disrupted. Tony was a key figure in terms of resources and leadership. Without him, the remaining Avengers might struggle more in their fight against Thanos. Peter, on the other hand, being young and full of potential, his presence could have added a different kind of energy to the post - snap world. Maybe there would be more of an emphasis on the younger generation of heroes stepping up earlier.
