Spencer's run is great because it fixed the character(s) and relationships as well as retcon Sins Past and did a good enough Job on OMD that we can move on to Pre-OMD style stories and made a great twist in that Peter and her Kid Mayday are the ones who bring Mephisto down in the present and future respectively and hence he targeted them.
So for Wanda you'll need:-
1)A writer who gets the character and has read all the comics w/ her(Spencer read all ASM and it shows).Maybe Zeb IIRC
2)They did do it in Children's Crusade, the real problem is no one cared for it and people like Wanda being the insane witch who took 95% of Mutant Population's powers/"birthrights" whereas all fans hate OMD and no other fandom cares for it either.
