My point isn't if they could or couldn't do things. From 2018-2019, Feige had a 5-year plan that he wasn't even letting the acquisition of Fox interfere with beside small things like being able to call Wanda "The Scarlett Witch" and use locations like Madripoor, which is more or less just set-up in the universe for something like a Wolverine movie or something down the road.With the rumors of Krysten coming back for She-Hulk, I think incorporating Jessica Jones characters isn't far off the beaten path. There's also a benefit that because Falcon and The Winter Soldier got delayed, they could work around this and plan ahead of time to ensure that it bypasses the date of which the rights rescinded back to Marvel Studios. It's unlikely, sure. But I have to think if it's someone major for the long term, that'd surprise people; incorporating Tennant would be a big one.
We'll see if Charlie and Krysten actually come back for SM: NMW and She-Hulk as has been the rumor. I hope so, I just am not getting any hopes up. I'm not expecting any mutants or any of that until 2023 or much from the Fox deal to be implemented until 2023 aside from the small stuff (when Fantastic Four comes out), but again, we'll see on the Netflix characters.
