Samoa has been down this road before.
The growth of the fleet from various aeroplanes such as the 727 to leased 737-300’s to the wet lease from air canada of initially a 767-200 which was replaced by a 767-300 which when that got taken home was eventually replaced wet leases of Dc10’s and L1011’s from various wet lease airlines then replaced by an orphan 767-200 from a middle eastern airline that had been invaded by iraqi’s and their aeroplane was the only one in captivity that had that engine/airframe combination (JT9D-7Q if I recall - but whatever the 747 version of the JT9D was) - so a winner from a ETOPS perspective.
eventually it pretty much sent the country broke.
