The Bianchi Boardwalk looks pretty close to being comfortable. I switched my 1990s Univega from a flat bar to a riser bar with 1 1/2" rise and slight back sweep. More comfortable for my neck, but a bit of wrist and hand discomfort on longer rides. I'm considering a curved arc bar with no rise to reduce the reach a bit, or possible an albatross or North Roads bar with only a little rise.
So it may not take much in the way of modifications to get the Bianchi where it suits you again. Same with the Specialized Roubaix. I've seen folks modify road bikes with the right stem, handlebar, levers/shifters and saddle to make them into remarkably good hybrids. And the sloping top tube of a compact frame bike might be easier to hoist a leg over.
