I think the Ranger hits the mark. It's the right size...if it were any bigger, I'd question why not just get a half-ton. There has to be some measurable difference in size to make a mid-size worth it. You want better fuel economy, which is a function of smaller size and lighter weight. You want it to be easier to maneuver and park, and yet still retain enough functionality to pick up a bedload of items at IKEA, or move an old couch up to the cabin.
I also think the 2.3EB is just fine, too. Ford is starting to perfect their EB engines (I think the 2.7EB is the best choice in the F-150 as a daily driver), so going with a turbo four cylinder in the Ranger makes perfect sense. I do think they could have more up-market Ranger with a nicer interior (Platinum Ranger, perhaps) and the 2.7, for those people who want a super-equipped small truck, but don't want to put up with the immense size of the F-150 just to get some massaging seats.
Ford will probably never do this, however, as they won't want to scavenge sales from their half ton.
