I really don't know whether it's possible, your the first to ask about such usage so right on the bleeding edge of OSG usage ;-) To support rendering to a 32bit floating point alpha channel you'll need to create a RGBA floating point colour buffer, copy the whole buffer to an osg::Image then pull on the alpha channel from this. Whether you can create a 32bit floating point colour buffer will be down to whether your driver and hardware can support it.
