Make server templates

I would like to see a template for the server, not a thing where you can change the whole look, but rather make it like for instance Clash of Clans templates where you keep all the existing things, but you can change the looks. And you then can make 3 presets to swap between. So that you change for example the following:

• Role names
• Channel names
• Category names

While you should not be able to change the server name, logo nor deleting channels/categories/roles.

This makes it so that you can remake/clean your "previous" server, but people would not confused about which server it is to the same extent as if you would change EVERY single thing.
