After seeing Homecoming, I am rather impressed about how Iron Man is incorporated. And in a sense, even if Tony Stark doesn't have a legitimate speaking role in the attraction, I wouldn't mind it.
Without going into it, there are ways that, as seen through Spider-Man that you can very well easily use artificial intelligence to tell a compelling story, and that it could be a great chance for them to market the attraction to BE Iron Man.
You don't have to use anything from the MCU, use the Modern Comics with a The Incredible Hulk asthetic, and that you can still use something that is compelling and exciting, while also using Iron Man villains from the comics not seen in the Marvel Cinematic Universe as it stands.
I am all up for a Non-MCU Iron Man attraction, and that I believe there are ways you can do it rather impressively without the need to bring Stark or Potts into the ride whatsoever.
Just my two cents on it, even though I wouldn't be surprised they reincorporated the Tony Stark voice actor of the Avengers cartoons; Adrian Pasdar (which was from NBCs Heroes) into the fold and do a story that is while unique to Amazing Adventures of Spider-Man, telling a story to where you help Tony while also tagging along with him, in custom created Iron Man suits that can accept people of multiple types.
