You should be able to copyChannel the BitmapDataChannel.ALPHA from the image you loaded onto the bitmap you use for the gleam. However animating this then means moving only a single channel. Which may or may not be possible without reprocessing the bitmapData. It's only a rough idea, but take a look... You could also copy the alpha channel onto all the other channels of a new bitmapData which will give you a black silhouette which you could use as a mask.
