No, to the swap
You can replace busted engine with same model, but swapping 3.0l for 4.0l would cost to much in time and money for results to be worth while.
You need to swap computer and engine wiring harness and as you said transmission.
So better just to sell the 3.0l Ranger and buy a 4.0l Ranger, or buy a 4.0l now if that's what you want
Since the time and cost is about the same the V8(5.0l) swap is more popular
