I would think just starting out is the perfect time to switch over to Python / Node / whatever... you've got your head around the concepts of MVC, object-oriented programming, etc, but haven't settled into a routine about how to use your particular language and framework. Once you're specialized, switching costs only grow.
Plus, if you hire a bootcamp grad, you're probably going to have to do lots of on-the-job training anyway. Good time to indoctrinate the candidate with the "right" way to do things in your particular codebase.
