Umm, I think that idea was widely discussed with the Thames estuary airport ("Boris Island"), which got killed off precisely because it was in the greenbelt! The local estuary bird life was apparently not keen on it...
Also, re-locating all the existing infrastructure around Heathrow (transport connections, cargo handling, maintenance, hotels etc) to a new airport would be massively more expensive than just building a new strip of tarmac next to the M4.
