I agree, cories are a schooling species. They shouldn't be kept in such small numbers--they won't be happy or feel secure in that setup.
To be honest there's just not many fish that can thrive in 5 gallons with a betta or without a betta. If I were you, I'd just settle for a betta with some snails, or shrimp if you must. Shrimp often end up eaten, however.
