Hmm yes you could use either an Alpha-texture which fills the complete screen and render it afterwards your scene has been rendered you can achieve this by overwriting postRender() in Canvas3D or a Raster-object which is basically also a texture. I tried also to write Alpha values in a background node before rendering but in my first attempt I completly failed. But I think Kelvin Chung noted that I'm doing something wrong I haven't tried it again though.
