I know you have the Ranger, so I understand that sentiment.
However, in the 80's and 90' the Bronco II and the Blazer S10 were much smaller, built on the Ranger and S10 platforms to make people like you, who appreciate a more compact truck more apt to buy into the name. Doesnt have to just be 150/1500 size. There IS a Bronco Sport now that could have been built on the Ranger platform.
I really liked that it was "truck, SUV and small truck, small SUV." Swapability was so handy
My wife has a 22 Bronco, I dd a kind of newish (2016) F-150.
The nose on the 150 is tremendous. Long hood, super deep dash, super wide. Its made for big engines and keeping them cool while towing. Since they already make a F-150 based SUV I am assuming you basically want a 2dr Expedition. Half the vehicle you couldn't do anything with... it would be hood and dash lol.
It would be silly to build the Bronco Sport on the Ranger platform when they are already making the regular Bronco on the Ranger platform... which is a global platform.
The BII was a throwback trying to give the scorned EB owners an alternative to the fullsize Bronco, they are actually pretty similar in dimensions.
Looking for dimensions for the 1966-1996 Ford Bronco or 1984-1990 Ford Bronco II? Check out the Ford Bronco dimensions on this page.

The BII eventually morphed into the Explorer which blew Bronco sales big and small out of the water and at the end of the day probably killed the Bronco (similar to the S-10 Blazer vs the K5)
I disagree somewhat. The Ranger and Broco are basically built for different purposes. As soon as you begin building them totally off of the same platform you begin having to deal with compromises. They do have similarities in some areas. Engines are pretty much the same. Transmissions likewise. I don't know enough about either of them to know of other similarities, but I don't think there is a need to have swappable stuff. If you need a part for a Bronco, get one for a Bronco. Same goes for a Ranger.
I think the only thing that using the same platform provides an advantage to is the manufacture. Having more parts that can be put on two of more different vehicles helps to lower the cost of making those vehicles. I doubt much of that is passed on the customer. The customer is the one ends up with the compromises.
Actually the Bronco's Ranger roots gives it the common 6 lug wheel bolt pattern. So it can use the same wheels as a Toyota or Chevy. Unlike the F-150 that can use any wheel it wants as long as it is for an F-150...
Swapability is a good thing though, one off stuff is less likely to be in stock. A starter that is only used on one model may not be stocked at a parts store, definitely not to the same inventory levels as a starter that fits five models that will see much higher demand.
