I see your proposal, and raise it: Gwen tries to do it as you say, fails, gets depressed, but comes to a realization that she isn't as powerless as she thought. Characters act differently depending on the writer. Canon from one run to another is flexible. End the arc with Gwenpool carving out a section of her comic where MJ and Peter *do* beat Mephisto, DO save their marriage, DO get to live happily every after... knowing that it isn't canon out there, but it IS canon in here. A tiny seed an idea that things can be better. A spark that, if she is lucky, might grow into something bigger. And if it doesn't grow... at least she can keep it alive in this place so its not lost entirely.
Basically saving Spiderman's marriage and putting it on a life raft adrift in the comics continuity multiverse in the hopes that it will find safe harbor somewhere.
