Love this analogy. I'll try to interprete this and let me know if I'm making some mistakes.
Your enhancement already used in other project, hence you have several options:
1. Get rid of existing implementation in that enhancement and put your code in it.
2. Write your code after existing codes, means that existing code will be processed prior your new code.
3. Write your code before existing codes, means that existing code will be processed after your new code.
This is a nice blog that discuss on how to implement option 2 and 3 elegantly.

If you can find multiple implementation Badi that can be used for your requirement, it always the best approach. However, if you can not found it, try check on that blog and apply it if needed.
