I mean, considering they've already wrote the thing and are in the process of filming it, it doesn't seem veyr likely.
The movie is written and filming now. That ship has sailed.
Let's wait till the next movie, bro.
Everyone beat me to it...
I don't see them retconning Skeeter this movie, next movie or any movie in the future. She's a one off character created to add a female character to a mostly male line up, and she was specifically created over using existing Janice because it was, in fact, required by law to add an athletic character to a child cast of an 80's cartoon series. They never intended to mix the character in with the pre-existing ones outside of that.
Roger and Amy were able to use her in the comics, only under specific circumstances that it's canonically ambiguous if it's happening or not (which I don't see why she's any less valid than Ninja Rogers or Clint Wacky as a comics specific character). They made her the strong female character that, let's face it, we wouldn't have got if she was retconned in the past. We'd get basically girl Scooter, not the amazingly fleshed out and well designed character from the comics. It would be great to see her in a Muppet project, but that's about as likely as Nintendo giving the time of day to any of the cartoon shows based on Super Mario.
