Is it possible to make JFBc into a module?

I'm not sure exactly what you're looking for here. JFBConnect includes the SCLogin module, which is based off the standard Joomla login module and adds the social login modules (along with a lot of other configuration options).

Hopefully, that's all your looking for. If not, let us know more details about what you're trying to setup and we can gladly point you to other options to do so.

Thanks,
Alex
