[RMMV] HAS ANYONE MADE A PLUGIN FOR SWAPPING TILESET IMAGES?

Let me start by saying that if this is the wrong section to ask this, can someone move it?

I realize at one point someone made a script for Ace that allowed literally swapping out the tileset image it's self.. replacing the image.. rather than making multiple tilesets and swapping them to do animating, I was looking for a plugin that let me have ONE tilset with everything set up such as where you can walk and what not, but then swapping the image it's self.
I have a coastline that animates waves, but the way I have to do it now is by making multiple tilsets and swapping them out to make the waves animate, it get's a bit annoying after awhile because if I make simple changes or add graphics to my tiles like a new OW City graphic or something in the B or C, I then have to go back in to each tilset one at a time for the A5..
It's just becoming very annoying and stressing to keep doing that.
So I was hoping by now their might be a plugin that lets me swap the tileset images for a Tilset to do my animations, rather than having 5 slightly different and swapping them in and out, I can just swap the images themselves for the A5 for instance..
It would make the process a lot less annoying.
I have been looking all over, and so far I have not found one.
But I figured something slipped through my fingers.. so I thought I would ask.

No... no.
I mean the IMAGE used FOR a tileset.
That changes the MADE tilset.
I want to change the image used FOR a tilset.
I'm basically trying to animate my maps using the A5 tileset image.
A similar script exists for RPG maker VX Ace, where in you can swap out the image for in this case A5 without actually making several tilsets.
Oiveh...
