Around the World in 80 Days

I'm going to be replacing my aging 1GHz Athlon with new and much faster machine in a week or two. I though it would be fun, rather than flying around aimlessly has I had been doing, to plan a trip around the world. My criteria would be to fly one type of aircraft. One which would be able to land at all airports (well, nearly all) and not make my circumnavigation a trivial affair. So that means no Lear jets or 737's. I'm thinking that a King Air would probably fit the bill, but I was wondering if anyone had any better ideas. Secondly, I have to figure out a route. I would like to fly into some of the more interesting airfields, Lukla springs to mind. Since there are a multitude of excellent add-on's here in the Avsim library, I'm not short of options, but again would appreciate any ideas. I also need a pick route with legs short enough so I won't run out of fuel enroute. I was thinking about a West to East track, mainly in the Northern Hemisphere, to take advantange of the winds.TIA,Andy
