Best way to change the file listing view to display data from 2 servers


I am working on a project aimed to use 2 servers (one acceptance and one production) which should display info about one folder in the same file listing page.
The paths from Acceptance and Production servers will be the same so what I am trying to find is the best approach to get data from both servers and display this data in one view.
For this I am working with external storage SFTP
In the file view I should be able to display metadata for one file (i.e. size) from both servers.

Let me know if there is any way to inject this information trough existing implementation or the entire flow needs to be updated (starting with file caching, fileinfo, node, filePlugin etc. )
