QImageBlitz seems to me to just operate on single images and not composition so the blur itself could perhaps be done by QImageBlitz but the blend would still be separate.

However the blend itself is just a simple Porter-Duff operation as provided in QPainter and X Render (looks like the SourceOver operation offhand but I'd have to look it up) so maybe we could use one of those instead?
