I am hoping that this crossover will happen. The way Square Enix bought out TAITO, it doesn't look that way. The way I would see it go is Bub and Bob getting Disney makeovers and becoming Phineas and Ferb's new pets. Bub and Bob become OWCA agents and after the movie, everyone that was in the fight become agents as well. If you guys wanna see the way i would do this, view my story on my fanfiction.net account named PnFBAMFan. The story is "Phineas and Ferb Bust A Move".
