From what I understand about Schizophrenia, I would expect limited potential here at best. The schizophrenic brain is structurally different: for instance the hippocampus of schizophrenic people is disorganized, and schizophrenic people have less gray matter than neurotypical people. It's plausible that to some degree these changes could be reversed to some degree long term of they're the result of a tonic stress from the gut biome, and it's also possible that acute schizophrenic episodes could be ameliorated if it turns out they're triggered by the gut, but it's highly unlikely that replacing the gut biome of a schizophrenic person would give you a neurotypical person. The other thing about schizophrenia is that people usually develop the disorder in their late teens or early 20s with an acute episode. If there is indeed a link to gut bacteria, and if you could identify pre-symptomatic, high-risk individuals, I would imagine this could create a very compelling vector for preventative treatment.
