Thumbnails instead of filenames as tab titles on the Photoshop workspace

Would it be possible to have thumbnails of the file image in the tab titles instead of the filename? I often work with 6+ images open at once in Photoshop.  Currently I can only see 3 or 4 tabs as the filenames are too long to allow more tabs. If the tabs were thumbnail images instead of filenames then there would be more space for the tabs in the workspace.
