Looking for plugin or tool to find and swap already applied color variables

Hello community. I have reusable design system which contains next files: Design token (where located all variables) and Components (where I have all needed components controled by variables from previous file). When I start new project, I duplicate that two files and swap libraries to connect them to each other. The problem is that color variables applied to components are still related to old token library. 

Currently I need manually replace color variables by the same variables from new (just duplicated file). 
Maybe there are any plugins or tools that can automate this replace/swap color variables process.
Thanks :)
