Boy, I'd love to do that (wouldn't we all?) but I'd have a hard time picking what kind of frame I'd want to build.
Sure sounds like a great thread to me! I'd go with something in between a sports tour style and a relaxed road bike. Sort of rando'ish, but more cinelli model b. I'd go high bb, room for 32s and fenders, rear rack and set up for Paul mafac style brakes.
