The fact that a small aircraft is capable of flying long remote routes, does not mean it necessarily should. Meeting the minimums of aircraft equipment and survival equipment has got many pilots across - with luck. Other pilots did not have enough of either....
There is no margin for error, or things going wrong on this route. My opinion on this is based on my experience.
Is it really worth the high risk?
You could reach three coasts, and see this - it's beautiful, but it could be impossible to pass over....
