Multiple Source Locations for a single Item

Here is my situation. I work at a community college, and we are deploying Kodi as a replacement to Windows Media Center as a client for our media server. The problem we have been faced with is that we currently only have one media server for both campuses, and if it crashes then we have to take a day rebuilding the server. What we are thinking of doing is hosting two servers, one for each campus, and we would sync the media across both. This would allow the faculty and students to have access another server if one were to crash.

So here is our dilemma. I am trying to figure out a way where we can sync both servers to Kodi without showing duplicates of every item. I tried showing each item as a set, but that confuses faculty, as does having multiple profiles. Does anyone have a solution? My boss doesn’t want to host an SQL server, or use Plex, Emby, etc, so I have to solve this using Kodi only.
