I'll give you an alternate idea. Keep the steel fork. Use a threaded-to-threadless stem converter, and a threadless stem coupled with a modern carbon road bar. Those can have varied flex that will absorb road buzz and offer you some varied hand positions.
Note the sculptured contour on the outer curve. Very comfortable. Plus, this will allow you to run the cabling internally, cleaning up the appearance. Anyway, who doesn't like to have options?
