What if...in the real early 1900's...Greece took Tonga?

Ok. A funny thing I thought of, thanks to a Greek coworker who was thinking of taking over a small island state...he thought Pitcairns. Anyways, another thought came to my mind...suppose, in the early 1900's.....Tonga was conquered by the Greeks? I know, farfetched, but what if?

Would Tongan use the Greek alphabet?

Would the monarchy be left intact, would the Tongan crown be assumed by the King of the Hellenes?

What if?
