While the story of Peter and Mary Jane's daughter (Mayday) is no longer cannon, would it be possible to have May Parker(Venom) of Earth-9997 to reside in the mainstream Marvel Universe (Earth-616)? It might be a nice touch to bring this version of Mayday Parker into the mainstream since she is quite different from her Spidergirl counterpart of the MC2 Universe. This might help to resolve the gap that a lot of people felt about the child that Mary Jane and Peter Parker will never have. This would be no different from Rachel Summers, who is from Earth-811. Why can't we have the same for the Mayday Parker of Earth-9997, which is quite similar to Nocturne, the alternate reality stranded Daughter of Nightcrawler? It would make for an interesting story that Peter has a daughter who is also his partner in fighting crime.
Of all of the Earth X characters, the May Parker version of Venom is awesome. I certainly would love to see her join the Exiles and become friends with Nocturne. Since the characters of Earth X are no longer be used, wouldn't be a good idea to consider bringing back May Parker from that series into the mainstream Marvel Universe since it would not conflict with the current Spidergirl (Araña). In my opinion, this might relieve all of the negative reactions that was done to Peter and Mary Jane's marriage in the One More Day storyline, as well as the Clone Saga series. Despite the notion that Rachel Summers and Nocturne are from alternate Earths, they still formed a very close relationship with their respective fathers of Earth-616. Don't you feel that Peter Parker should have a similar relationship with May Parker from Earth-9997(aka Earth X)? Since Joe Quesada originally wanted to bring the May Parker version of Spidergirl into the mainstream Marvel Universe, the May Parker version of Venom is a good alternative because it makes a lot of sense to do. Don't you agree?
