Forget my theory...

Its too far fetched. It is very unlikely that they'll such a thing happen. They're probably gonna just use Perry and find some stupid reason for Monogram to give Perry a mission to go to another dimension. Its like they're trying to find the idea that would sell the most. People want to see Phineas and Ferb find out who Perry really is, so they are gonna use that as the selling point of the movie. Heck, I wouldn't be surprised if they added certain character relationships in order to get even more ratings.

Either way, I still look forward to this movie, even if it has a ridiculous plot.
