So, would this be the procedure?

Suppose you have the following set of files for your project, for
simplicity's sake:

   Board.pcb
   Schematic.sch
   XYZ123.fp

Suppose further that you have 50 instances of XYZ123 on your
schematic.  You really don't want to do this manually.

1. search and replace with sed or ? on the file Board.pcb to replace XYZ123.fp with XYZ123_new.fp

2. Replace all instances of this in your schematic with the temporary
    name:
    sed -i -e 's/footprint=XYZ123/footprint=XYZ123_new/'

2a.  create file XYZ123_new.fp

3. Open the layout in pcb and update the layout from schematic.
    pcb Board.pcb
    Execute File | Import Schematics.

4. You might have to fix some components, they sometimes are
    rotated incorrectly after being updated.  Use the rotate tool
    and click on the component reference point (diamond) until
    things are lined up.

5. Save the layout.

But now you have a name of XYZ123_new.fp.  How do you get to modified XYZ123.fp
in fewer steps that Colin suggested?  Or are you suggesting always use anew name?
