While I don't think any of the kids will be made canon, on the small chance that Marvel decides to go for it, it'll likely be Mayday, she has the biggest pull, Annie's popularity was too brief, nobody cares about Benjy, and I'm pretty sure nobody remembers Claire (And maybe she's a Mayday counterpart so we shouldn't count her too lol).
She does comment on occasion how costumes make her butt look like, so maybe she likes to flaunt it
.
Oh so that's what the graffiti besides the heart says, thought it was random gibberish lol.
RYV has the biggest change in its timeline at around Civil War era, but it's probably even earlier since I doubt JMS' run happened (At the very least, he definitely didn't fight Morlun, and considering it looks like aunt May has her old hairstyle when she's dead, she likely died in the 90's era), so Gerry can have been born at some point if she didn't die randomly, specially considering that in both MC2, where she didn't get her powers back, and in 616, where she did, Gerry was born despite the very different lives they both had.
Basically, if Gerry doesn't exist in RYV, that'd be more surprising 'cause he looks like a multiversal constant.
