I feel they'll slowly step away from all the first wave of characters, especially with F4 on the horizon and X-Men still in the wings. My daughter was quick to point out that Wandavision seems to take directly from the House of M storyline, and after a bit of research, I'd definitely agree (she outnerds me time and time again, so proud!!), which may serve as a place to start bringing the Xmen universe in. As long as they hold the quality, Marvel nerds will show up.
