That could be done but it's not straightforward; you'll get a lot of overlapping postcode sectors and sectors with non-contiguous parts. GeoLytix produced an open dataset like that some time ago: http://blog.geolytix.net/tag/postcode-boundaries/
In my view, inferring polygons is something that should only be done in the data consumer, as they involve creating data that cannot be justified from the input data.

I don't know how many that would give, but it would be a whole lot less than 500k and still at a very usable level.
