Bianchi Girl could post up her carbon K2 as her build was along these lines. I guess your pretty much limited to bar end shifters if you don't want to use STI/Ergo shifters on a newer bike since they don't have the bosses for downtube shifters most likely. I have a Selle Anatomica leather saddle on my bike that has a 11spd carbon Campy group, aero Reynolds wheels and all that other business you'd find on newer bikes. I'm in for the comfort and not being a weight weenie too much anymore.
