I am only wanting to do this for future book sideloads so I am fine with fixing it one book at a time.
I have tried fooling around a little bit with editing ASIN numbers but nothing has worked so far.
Any ideas other than upgrading device/laptop?

Thanks,

I am not a wizard, but I think you can use https://github.com/rupor-github/fb2converter for that. Most of its functionality will be useless for you, bit "synccovers" subcommand will do exactly what you are looking for:

Code:
fb2c help synccovers

NAME:
   fb2converter synccovers - Extracts thumbnails from documents (Kindle only!)

USAGE:
   fb2converter synccovers [command options] SOURCE [DESTINATION]

OPTIONS:
   --width value   width of the resulting thumbnail (default: 330)
   --height value  height of the resulting thumbnail (default: 470)
   --stretch       do not preserve thumbnail aspect ratio when resizing (default: false)
   --help, -h      show help

SOURCE:
  full path to file/directory on mounted device
DESTINATION:
    always a path, output file name(s) and extension will be derived from other parameters
    if present - converter will not try to construct kindle thumbnails directory, will use destination instead

Synchronizes kindle thumbnails with books already in Kindle memory so Kindle home page looks better.
In should run on Windows from 7 up and does not require installation.
