Interesting theory. But when I did the analysis at the time my conclusion was that it landed in Southeast Iran. Engine ping data was one clue. It was then refueled and flown to another base were it could be hidden. Why did the Iranians want it? So they could put a nuke on it and fly it into Israel. All this hype about that Iran is two weeks away from enough nuclear material to make a nuke is crap. By my count they have 6 nukes already. I expect the first few were very primitive ones and quite large. Too large for a missile. And it would be a lot easier to get the nuke into Israel by aircraft than missile. Missiles would follow in the confusion. The discovered tunnels were meant for Hamas to flow in and finish the job in the chaos.
