Actually, it might be possible:

In `buffer-undo-list', one entry type is

    An entry (apply FUN-NAME . ARGS) means undo the change with
    (apply FUN-NAME ARGS).
    
    An entry (apply DELTA BEG END FUN-NAME . ARGS) supports selective undo
    in the active region.  BEG and END is the range affected by this entry
    and DELTA is the number of characters added or deleted in that range by
    this change.

This can be used to do anything for undo, including editing other files.
