Maybe, the board needs to change the by laws and just add one additional non Hawaiian member receiving the highest number of votes.
Correct, changing the by-laws to drop the Director residency requirement - as required by Hawaii statute - is certainly the correct solution.
Unfortunately changing the by-laws is not something the BoD can unilaterally do, and is almost impossible without Wyndham's 20% of the voting power. Which - as I have commented on extensively - is the issue the SaveKBV.org assumes away. There is no path forward without Wyndham's buy-in and cooperation, and continuing to paint them as the villians in this narrative does nothing to address the long-term issues facing KBV.
Because this is not Olympic Village where the owners are trying to keep Wyndham from acquiring ownership interests. Wyndham owns the deeds they own, and there is very little to be done to change that. Assume for a second that the SaveKBV.org gets everything they have asked for - election is invalidated, new election is held, new BoD is seated. Wyndham still is going to control multiple seats on the BoD.
