[XP][SCRIPT REQUEST] MASKING ANIMATIONS TO BATTLERS

Does anyone have, or know of, a script for RMXP that enables the game developer to mask animations to battlers? Or, failing that, would someone here be willing to code such a script?

For the purposes of clarification: When I speak of masking the animation, I mean displaying the animation in such a manner as to prevent portions of it outside the battler's edges from showing. If the description isn't quite clear enough, please view the images below:

If you start with this:


And apply an animation cell looking like this:


The end result should be something like this: (Effect brute-forced in MS Paint)



If I'm allowed to post my 'dream list' for the effect, I would prefer a script where the developer using it is capable of designating specific animations, and specific cells within the animation, as being either masked or not masked...but at the moment, I'll take whatever anyone else is gracious enough to offer in this direction.

Again, does anyone know of/possess such a script, or would be willing to create it?
