Thanks a lot for all the comments.

I might go all the way with the PC12. It is not them most beautiful of aircraft, but quite practical. Next steps planned are Faroe Islands, Iceland, Greenland, Newfoundland.
The Pacific will be a challange. I decided against going via Alaska and the trip from California to Hawaii is a bit far for the PC12. I might go all the way down to Chile and then hop via St. Fernandez and the Easter Islands... let's see.
