even IF you put large electric motors on the wheels

you have to generate the same amount of power to move it as before when it was driving the wheels directly, you are still moving the same weight, maybe more
No, you could put a "smaller" more efficient isb type engine (maybe smaller) for the generator instead of an ISL or even larger engines in a prevost. Then for acceleration and hills you would tap a large battery bank for on demand high HP. Similar to many hybrid cars for sale today.
Basically friegtliner has to design a hybrid chassis people would want.
The main complain about hybrids in California is that the battery boost has limited capacity. It will help on 1/2 mile grade, but we do have several grades in 7 to 25 miles long.
20 years ago I did own couple of motorhomes that would take those grades at 25mph.
Not something I would look forward in new technology.
