I think I found the answer to my question above.
My wife's coworker who has a Dream Key Pass says he's done that many times already, so my only concern is "however, reservation requirements are subject to change." Hopefully this helps out anyone else in a similar situation.
Also, am I the only one that has zero hype for Avengers Campus? I mean, I'll try to get on WEB Slingers and explore the land and any roaming characters, but I'm not expecting much. None of the food offerings are interesting at all.
Park Hopper Tickets
Guests who purchase or have a Park Hopper ticket and an appropriate park reservation may cross over and switch between parks on the same day beginning at 1:00 PM. Please check the Park Hours calendar and the Disneyland app for the most up-to-date Park Hopper hours, as they could start earlier at a later date, depending on the day and park. Guests with Park Hopper tickets must make a park reservation for the first park they plan to visit AND enter that first park prior to visiting the other park. At this time, a park reservation is not required after the first park; however, reservation requirements are subject to change. Please note that the ability to visit the other park will be subject to that park’s capacity limitations.
