What you're suggesting would be that, say, a wall image, can just "change" to one of 256 predefined 256-color pallettes.
But what if the wall uses a completely different pallette order? What if the wall goes Black-Green-White and all the other backpals go Red-Yellow-Green-Cyan-Blue-Magenta? The wall will be yellow with red grout for every pallette you use on it, with very slight modifications.
Easy fix, just make sure the target image uses the standard pallette. But how many people are gonna figure THAT one out?!? "I tried to use the cool blue pallette on door.png, but it didn't work! It came out all black and stuff!"

i am not sure how to describe any better than I already have. Since each image would already have its own palette, you cycle its palette. No need to use the "standard" palette. The command would cycle the colors of the image's palette.

Look at the animated gif I have attached and notice the bottom right corner
