Hello,
Not sure if you are still needing this, but I had exactly the same situation as yours. I had button that have crazy conditions with multiple fields and needed to be used on many different field groups.
So I’ve created acf-component-field plugin, that does exactly what you described. Component Field Group are reusable and nest-able, with no extra php functions or classes you’d need to initiate in your theme.
Demo can be found here: http://gummi.io/acf-component-field/
Please feel free to play around in the backend and see how it’s setup.
I hope this helps you and anyone else who’s looking for this type of functionality. 🙂
