Unbeknownst to most, they actually already kind of did, yet didn't in Dr. Strange: Multi-Verse of Madness. What do I mean by that???? Believe it or not, they actually shot your answer to your question, but eventually cut it from the film. Check out the video below. The original intent for opening MOM was to have Mordo go to Wanda to kill her, but then Wanda actually kills him. Instead, they clearly opted to cut this scene in order to have the Wanda being evil reveal be a surprise for when Strange shows up. In fact, that picnic basket next to Wanda in the orchard was rumored to have Mordo's head in it. Anyway, take a look at the video below, as its investigation into this is quite interesting. Maybe that satisfies your question, maybe not.
