hmmm.. you could try
Take one of the indexed images and adjust the colormap as required. Export it for use.
An open image shows in the palette dock. Make a note of where it is.
Open your images, choose one. Use Colors -> Map -> Set Color Map and choose the palette from the 'adjusted' image.
Onto the next image and use Filters -> Repeat Last (ctrl-f)
An animation of that: https://i.imgur.com/oewSbFw.mp4
If that works with your images there is a script that saves all open images. Otherwise it might be possible with ImageMagick but I need to look that up.
