No, you can only get cleaner data and maximize the pixels you have, not more effective pixels. The way you could get "more" data is to simulate, say, a 28mm equivalent lens with, say, multiple shots from an 135mm equivalent lens at different locations and stitch them together.
Thats what they do when you see those 3GP+ shots you can zoom in on.
You an absolutely gwt subpixel detail by averaging multiple photos taken with the same setting with almost exactly the same frame. I had software in 2004 that did this, converting short video to high res photo
