Unusual question as I book my next RTW:

On my first I prioritized getting:

• HEL-LAX for the strange line on my lifetime flight map
• SCL-SYD for my first south pacific crossing
• SYD-JNB for the Antarctica crossing (already did PER-JNB on SA years ago)
• SYD-NLK and SYD-AYQ because these are normally insanely expensive if purchased on their own

My question to the OW gurus (since I'm a Star Alliance guy usually): what other "unusual" routes could I add to my next OW RTW? Looking for unusual flights, fun lines to add to the lifetime map, etc. I'll attach the map for reference...I'm already planning HEL-SEA for the line when it opens up so that's on the map in white...
