I think that information about file names is redundant.

To restore file buffers in windows of the saved window configuration,
you can prepare buffers (open files, call packages that create special
buffers, etc.), keep their buffer objects and use them later during
restoring the saved window configuration.  For instance,

(setq buffer1 (find-file-noselect "file1.txt"))
(setq buffer2 (find-file-noselect "file2.txt"))

(set-window-configuration-from-list
  '(window-configuration
     (frame-cols . 80)
     (frame-lines . 41)
     (window
       (buffer . buffer1)
       (left-col . 0)
       (top-line . 5)
       (total-cols . 86)
       (total-lines . 35)
       ...)
     (window
       (buffer . buffer2)
       (left-col . 0)
       (top-line . 5)
       (total-cols . 86)
       (total-lines . 35)
       ...)))

This is basically what desktop.el does: it restores buffers, and later
it can restore window configurations using restored buffer names.
