On a slightly different subject (though still topic/Ridgeline-related), Ford should consider bringing back the Explorer Sport Trac (which was essentially a four-door Ranger with a short bed). That was a real body-on-frame truck, done on a mid-size chassis just like the Ridgeline, and more versatile because you could do mild off-roading and tow heavier loads. It also had a flip-down bed-extender (with the tailgate down), for longer loads.
Now that Ford is looking into bringing back a slightly larger, mid-size Ranger pickup and two-door Bronco, it probably wouldn't take much additional tooling to do another four-door Sport Trac. It would probably decimate what few Ridgeline sales there are, except for die-hard Honda supporters. A close friend of mine has a 15-year old, 2001 model Sport Trac that has been useful, reliable, and still runs quite well.
