Alternative to the spatter filter, for use with DOM scripting?

@hertze 

Like so many things in Photoshop scripting, I don’t believe that it is available via the DOM, which leaves AM code. 

Spray Radius = 10

Smoothness = 5

spatterFilter(10, 5);

function spatterFilter(radiusValue, smoothnessValue) {
var idGEfc = charIDToTypeID( "GEfc" );
    var desc533 = new ActionDescriptor();
    var idGEfk = charIDToTypeID( "GEfk" );
    var idGEft = charIDToTypeID( "GEft" );
    var idspatter = stringIDToTypeID( "spatter" );
    desc533.putEnumerated( idGEfk, idGEft, idspatter );
    var idsprayRadius = stringIDToTypeID( "sprayRadius" );
    desc533.putInteger( idsprayRadius, radiusValue );
    var idsmoothness = stringIDToTypeID( "smoothness" );
    desc533.putInteger( idsmoothness, smoothnessValue );
executeAction( idGEfc, desc533, DialogModes.NO );
}

EDIT: Another option to roughen is Pixelate > Crystallize

crystallizeFilter(3);

function crystallizeFilter(crystallizeValue) {
var idcrystallize = stringIDToTypeID( "crystallize" );
    var desc569 = new ActionDescriptor();
    var idcellSize = stringIDToTypeID( "cellSize" );
    desc569.putInteger( idcellSize, crystallizeValue );
executeAction(idcrystallize, desc569, DialogModes.NO);
}
