I would recommend against exporting the palette from PalSuite since it couldn't account for any colors being moved around in the palette among other things (same issues with IrfanView). You would also be blindly applying a palette to an image, which you couldn't easily undo. I updated my last post, and so TilesetPal would be the easiest way for you to load the edited palette into an image (just make sure to at least mark every palette index as "Don't Change").
