Java Code Simplification Tool

I'm so tired of using Intellij's code refactoring and others such as openrewrite and sonarlint. These are great tools but do not solve the problem for code simplification. Any tool currently available which simplifies large clunky code? I could build this on my own as well as part of Intellij plugin marketplace. Basically it should not "suggest" but "execute" removal of dead code, merging of over modularized methods, merging of useless classes into one, merging of scattered enums into on enum file. Thoughts on this?
