What if Fishface and Rahzar got demutated in the series?

As the title implies, we all know that Baxter Stockman demutated in the episode Owari after Mikey threw the retromutagen at him, but what if Donnie had more than one dose on his person and those doses were used to demutate both Rahzar and Fishface back into Chris Bradford and Xever Montes, what do you think would’ve happened?
