Wanda reached out to Jeen when Jeen was struggling with the Phoenix. So it has happened. Writers were not able to follow up with it because Jeen went to the past. But now that Wanda has made amends with Krakoa, it could happen.
I view Wanda and Jean as very different characters. However, they have know each other for a long time and it would be nice to see them interact more often. I think if we see Wanda on Krakoa more it will happen. Cross your fingers it will happen during the Hellfire Gala.
