Here's the thing about that, though...

I'd have to give their pet, Tommy the Platypus, an antagonist if I were to make him totally like Perry. Here's the thing, though - the OWCA is openly allied with TerraFleet, and Perry works for the Animal Division of it. And Tommy is openly acting humanoid in Ad Astra 2: Youth and Nostalgia, so the idea of a secret agent organization is kinda out of the question...

And since both Chris and Erica are inclined to build stuff with the help of their parents, there's really no one to try and "bust" them like Candace back in that generation. So...how would I structure it? What kinds of twists and turns could I add that would make that kind of spinoff anywhere near the caliber of the actual Phineas and Ferb TV show?
