I currently don’t have a plugin that adds bitmap composition to side-view battlers. (Dynamic Pictures only works on Sprite_Pictures showing Game_Pictures, usually shown with the “Show Picture…” command.)
The main reason is that the games I’m contributing to don’t use the side-view battle mode. If your game uses a Picture to represent the player character(s) and/or enemy, then Dynamic Pictures would work for that. Otherwise, a plugin layering battler bitmaps is needed.
The cleanest way to tie my plugins together is through their JavaScript APIs. I could make a plugin (at no extra charge) that specifically targets Actors and sets up those rules in both Dynamic Pictures and Dynamic Characters at once. It doesn’t sound like that would fit your use-case, though.
