Hey Ryan!
Why not do just what you are doing - break the epic trip into smaller sections, just land at the end of the sections. "Fly" from NY to Greenland, Greenland to Iceland, etc. Enjoy the "flight". Many of us do these epic "flights".
And, it is "different" to operate the rudder pedals (landing & taxiing) with a full bladder, while a turd is playing peak-a-boo with you, while you're trying to pay attention to what you're suppose to be doing - which should be operating the aircraft properly and safely. Some furthur advise from Jack Nicolson (in the Bucket List, I thnk), "never trust a fart".

I've commented about people who turn on the auto pilot, unlimited fuel, auto everything and let the flight simulator act like a wall clock... Kinda useless...
Blue Sky Wishes,
