Comment (by psykro):

 Right, first attempt at suggesting a possible way forward. To my mind, the
 simplest way would be to check the zip being installed against any
 existing possible matches, before the actual file is uploaded.

 Plugins-Step-2-Confirmation.png)]]

 So on adding a new plugin and clicking the Install Now button
 1. Make a WP Rest API call to check if a plugin with either a full or
 partial slug match exists
 1. Display the 'This plugin you are attempting to install seems to exist'
 message to the user
 1. Display the matching plugin details (name, description and version
 number)
 1. Move the Install Now button under the 'confirmation' message and change
 it to 'Accept and install'
 1. On clicking the install button the usual upload and install process
 proceeds

 Things to consider
 1. During the upgrade process, the plugin being overridden should probably
 be renamed/moved to a temporary location, in case the plugin install fails
 and a rollback is required (sometime like rename to _plugin_name
 1. Once the new plugin has successfully been installed, clean up the
 temporary location at step 1 above.
