Great work! There are several directions where you can make your work more substantial. For once it would be interesting to see what's the marginal benefit of iterative minification over iterations (can be represented in a graph). Does Remynification approach an asymptotic size value, will further minification actually increase the size instead of decreasing? Also, it would be interesting to take screenshot using selenium as suggested by sbierwagen and see if Remynification actually preserves initial layout. Lastly, it would be interesting to see a theory proposed as why such method work, and what can future minifier learn from this.
