A. Check if ThemeKit has an option to create shortcuts for customized icons. You can often create a new shortcut on your home screen that links to the app with a custom icon. Look for a 'Create Shortcut' feature within the app settings.

B. If ThemeKit does not support this, consider using a third-party launcher like Nova Launcher or Apex Launcher, which allows for extensive customization of app icons, including the ability to change original app icons.
