Is there a way to overwrite the core functions without creating a plugin?

Question

I would like to overrule some core functions using e.g. qa_register_plugin_overrides(), but it seems like I can only call this from a plugin.

I don't really like the idea of these core functions being overruled in a plugin, since in my case it is not a set of function doing one thing (like a plugin), but a collection of function overwrites that has no combined usage at all. Is it possible to load the overruled functions via an other way?

You can just change the Q2A code if you're not worried about ever upgrading.

Otherwise, just create a plugin for your own internal use - I don't see why it would be a problem - you don't need to distribute it to anyone else!
