Maybe anything is possible, but what is likely?
In looking back at the old post you quoted I ran across this -
I'll predict that they don 't slide very far down the side of the reef before getting caught in pretty shallow water where they will stay forever, but I could be wrong.

Gary, what makes you think that the peices would get caught up in shallow water? If this was the case then the action of waves, tides and storms would be more likely to move the peices out of the shallow areas and onto the reef flat as when the waves hit the shallow areas the energy within tem is released.
I've done a lot of diving on reefs and they have an infinite number of nooks, crannies, protuberances, and coral heads to catch stuff. The TIGHAR theory also relies on this to get the aircraft pieces to the natives. If the plane went over the edge and did not get caught in shallow water then it would have sunk to such a depth that none of the pieces would ever have come back up because wave action does not extend very far below the surface and gets attenuated very rapidly. So it TIGHAR is correct I would expect some pieces to still be found at a fairly shallow depth that has already been searched by the ROV with nothing found.

I think Gary was onto something in that.
Which is sobering to me in that it seems IF the Electra had been ON Niku and did slip into the depths, she would have had to do a lot of parts shedding in the shallows on her way down to Davy Jones' Locker for that sort of parts migration and deposit to happen, otherwise the depths would hold her until some gravity reversal took hold or something...
IF she was there and didn't plunge so deeply as to escape the active surf, then it seems we ought to have found a wealth of junk by now: yes we have an anecdotal record of a 'plane' there, but generally where wreckage is within reach, I would *think* (not daydreaming) that all kinds of stuff might have gotten fetched off and used or hoarded such that it might be found in such a setting.
Of all the 'airplane parts' looked at from that island so far, only a sherd of plexiglass and 2-2-V-1 seem to have been serious candidates - and the latter at least doesn't seem to fit. I'm not sure what the odds are of other parts finding their way into the area you speak of, but it seems like a very remote possibility at best, IF the Electra was there.
Looks more to me as time passes and I reflect on the things considered so far as if deep waters are the place to look, notwithstanding the sonar 'anomaly'.
That said, there is an awful lot of deep water one would have to look through.
