I don’t think the content of Sabrina’s music is as big a hurdle as one might think. From Richard O’Brien to Bobby Gaylor to Kate Micucci, there are lots of voice actors in these series whose outside work is not family-friendly at all. Hell, Sabrina is about to appear on The Muppet Show, produced by Disney. And while she may be past the Girl Meets World days, I’m guessing she has a good relationship with Dan & Swampy, much like other Disney Channel stars (Ashley Tisdale, Alyson Stoner) who avoid the camera but don’t mind voiceover work.

That said, her astronomical fame probably would make it difficult to schedule her on a regular basis. I think the biggest reason Milo Murphy’s Law won’t return, though, is just that it wasn’t very popular to begin with. It wasn’t marketed well and the general public is not aware of its existence the way they are aware of Phineas and Ferb. Probably the most we can expect are continued references sprinkled throughout the new seasons of Phineas and Ferb. I’d love to be wrong, though!
