Any chance to get this working in Emacs/Evil?

First, thanks for your work! I missed this so bad in Emacs/Evil. 

I looked into how I could write this script in the same way in Lisp, which is much easier than Vimscript. But I have no experience with Lisp. 

So my question is if you are willing to write the same script for Emacs?  I would pay you if you want?
