Unfortunately that takes quite a bit of work to produce a UI for that kind of full Photoshop color palette management.

That's beyond what I can do in a few minutes with a script, you would need to develop something of that level of complexity on your own - I could try to help you out in some particular spots if you want to undertake it.
