Risky strategy as you have to do it on separate tickets (otherwise long-haul APD still due) and you therefore bear the risk of misconnects (and also have to plan on additional times to pick up luggage and reconnect, if they refuse to through-check luggage on separate tickets).
Moreover, as flights from hubs are usually more expensive, it remains to be seen whether you actually save that much, if at all, by doing that.
