Tried that a long time ago. Collapsing the ribbon still does not give the “old” menu options. In Word 2016, for example, just to get started there is no “Format” option; no “Tables” option. Can’t use prior Alt + commands using keystrokes. The ribbon menus are not at all similar, collapsed or not.
You can customize the ribbons.
Pull the “Tables” option out from “Insert” and make its own tab.
You can rename the “Layout” tab to “Format”.
The options are all there. If you feel that strongly about where they are, you have the option to move them.
