A second MCU Spider-Man: Far From Home saw Peter struggling with the concept of filling Tony Stark's shoes and becoming his own hero, a new trilogy could feature Spider-Man taking on the roles Iron Man held by becoming a leader. Furthermore, he could also become a mentor, helping train new heroes introduced into the MCU.
It was recently reported that Sony is hoping to produce Avengers: Endgame.
Assuming Peter Parker survives No Way Home and finds a way to restore the multiversal incursions of past Spider-Man villains, there's no telling what could be next for the MCU's Webslinger. However, a dynamic future for Peter Parker could see him becoming a leader just like Iron Man was. It's also possible he could help train potential Spider-Verse 2).
While Far From Home helped Spider-Man become his own hero outside of Iron Man's shadow, he could still take inspiration from Tony Stark by fulfilling his past role in the MCU. The older and more experienced Peter Parker becomes, the more it makes sense for him to step up and lead in a new trilogy of films. This could even pave the way for Spider-Man eventually leading the Avengers, or a whole new team of heroes.
In any case, a new MCU trilogy for Spider-Man creates a wealth of possibilities where Peter Parker could become even more of a prominent hero than he already is. While being a leader and mentor like Iron Man feels like a logical next phase for the character, there's no telling where the Wallcrawler could go next. That being said, it would certainly be fitting to see Spider-Man honor Iron Man by leading and/or guiding the next generation of MCU heroes.
