Will,
I'm very jealous.
If I had the holiday for a long trip these days with the criteria you specify then my 2 big things would probably both be extended roadtrips. One around Europe, hitting as many of the major climbing areas as possible (alpine and subalpine stuff plus obviously Ceuse, Buoux, Verdon etc). Probably trying to swing across the continent, maybe start in Spain in the winter and then move gradually back upwards throughout the spring before hitting the Alps and Dolomites and stuff in the summer. The other would probably be a similar idea but across the states - Yosemite, Squamish, Indian Creek, Red Rocks, Joshua Tree etc. Again you could probably start in the winter and move from place to place as the climate warmed up.
In terms of places to meet psyched partners, I'd say that at the campstes at Ceuse, Chamonix (Bernard's in Argentiere, where the conville people go) and Siurana are the places I've been where it would be easy to turn up and find a partner. Chamonix it might not be to do your exact routes of choice, but then alpine stuff is always going to be less compatible to random partner meetings than just turning up and clipping bolts. The others you should have no problem.
