How can we copy/clone a custom module?

How can we copy/clone a custom module?

I have a question from my client if it is possible to clone a custom module like "Car Offers" with the exact same fields. They would like to have custom modules like Moto Offers, Boat Offers etc.
The logic of using Layouts under one  module does not work well thats why they prefer the module duplicate.

The reason for this is that they do not want each time to ask the help of a developer to simple clone a module with the exact same fields (and API name fields).

Is there any workaround here?
