They can, Phineas and Ferb is a good example of this, or there could be either a continuation or a revival of a show. But there’s one problem, Dana Terrance quit working for Disney which I wouldn’t blame her by the way 😒. And even if the owl house did come back, it wouldn’t be the same w/o Dana, and knowing Disney’s track record when it comes to certain shows, they’ll probably screw it up somehow and it’ll be forgotten 😒.
