Save camera overlay image with photo

Has anyone figured out how to use the camera image overlay, but have the overlay image saved as a part of the photo, saved in the gallery?

Example, having a logo in the lower corner on top of any photos shot.

anyone, Bueller? Bueller?

You can try hiding all other screen elements and just taking a screenshot. Really big hack, obvi.

Titanium.Media.takeScreenshot(function(event)
    {
        var image = event.media; 
        Titanium.Media.saveToPhotoGallery(image);
 
    });
