I am writing this the day before the issue come s out.
What I realized a while ago is that they cannot just become married again, there is too much continuity crap to deal with. They have both dated other people for instance, you can't just pretend that happened. I would be willing, but there would be too many complaints and questions.
The best you can hope for is that the deal is undone, they remember they were married, and decide to do so again.
Maybe they will elope in this issue. Maybe in June, with issue #00, which is also the 60th anniversary of Amazing Fantasy #15 and the 35th anniversary of the marriage.
Hey look at all the continuity that was messed up when the deal was made.
It's magic, we don't have to explain it.
Best thing at this late date would be to undo the deal even if it means the end of Aunt May, they remember they were married, everyone else remembers the wedding yet thinks perhaps they separated or are still married and they go off and elope.
