Folks at Marvel were trying to figure out how to launch phase 4 of the MCU, incorporate the addition of the X-Men, the relaunch of the Fantastic Four, and help the MCU on Disney+ get off the ground, and Feige was like:
The meta goes deep on WandaVision. This bit might be unintentional, but there's poetry in Marvel Studios launching its first foray into TV shows with a show about TV shows. Some history:
The previous Marvel TV properties were (mostly) run by Marvel Television and Jeph Loeb. They did some brilliant work, but the MCU films largely ignored the goings-on over there.
Now everything is in one house. It has the potential to be a huge freaking mess.
Part of the problem is how to insert the "first family" of Marvel comics into the MCU timeline. The Fantastic Four are old-school. The MCU heroes we know looked up to them and went to them for advice. Now they are going to get an MCU origin story. That's a conundrum.
Kevin Feige is a big comic nerd with a whole team of comic nerds, and one of them was probably like:
"Hey, did you know the witch who mentored Wanda was a nanny for the Fantastic Four? Maybe she could be in this."
