London and Heathrow are famous or infamous enough not to need advertising under an alternate brand. Furthermore, it's best to name something new - it's much more difficult to rebadge something old under a new name and get people to switch names.
Airports are inevitably quite grim and functional when you pass through them on a regular basis. When debate turns (eventually) to R3 or T6, or the airport has an operational meltdown, do you really want the Queen's name drawn through the muck raking and recriminations ?
Regardless of that, Leinster airport in Australia already uses the LER IATA code
Perhaps something more cheerful and uplifting ? Prince Albert, the husband of Queen Victoria, was memorialised in the Royal Albert Hall.... a place most Brits associate with something fun and enjoyable
