Can I duplicate and update the library while still getting updates from original library?

I’m working on a project of creating a design system. Form my other team members want to use the same design system with different tokens. So if they enabled my library. and swap their token to their own it will work on that instance but, it will not keep persistent. Is there a way to keep it persistent?

Another way is duplicating the library, and making changes to the tokens in the duplicated file. Is there a way to get updates from the original file?
