How to quickly change multiple selected style names (paragraph, character, color palette) to another

How to quickly change multiple selected style names (paragraph, character, color palette) to another series name?

Due to work requirements, I often need to create many similar styles.

Sometimes it's paragraph style, sometimes it's character style, and these days I've encountered the need to create new color palettes repeatedly。

I want to quickly modify B-1, B-2, B-3, B-4, B-5, and B-6 in this example to A-1, A-2, A-3, A-4, A-5, and A-6.

Is there a script like this that can be implemented?

Thank you very much~

Seems like something that should be simple to script

But I'm hitting a brickwall with it - I can't seem to duplicate the swatch group with a script.
I don't know why some scripts come easier than others for me. 

I was thinking it would be easy to duplicate the swatch group and have an input for the new Swatch Group name - then rename the swatches as the group name sequentially

But everything I have tried doesn't work at all.
