Such a bike does exist: The Pashley Guvnor. Its made with Reynolds 531 tubing, Brooks B-17 saddle, has Schwalbe Delta Cruiser Cream 40-635 tires, a slack frame angle with reversed North Road handlebar and leather grips and can be kept as is or converted into a roadster. Pricey but your ticket if its what you're looking for. Nice path racer for the money!
