That would be a solution if the original goal was a hybrid, but those already exist. If the quest is to create a "Modular hybrid" take that one step further and have a light empty rear section with no drive for local trips. But if the goal is to add range to an existing small EV, substantially redesigning the chassis seems out of scope.
The toll comment was to avoid doubling the fee with a third axle. My uncle tours on a Harley with a "large suitcase" sized trailer and pays more in tolls than a four wheeled box truck.
A thought just occurred to me. Thinking of those tiny trailers that connect tandem trailers for highway travel in the trucking industry. What if there was a range extending diesel axle module for EV delivery trucks that could be left behind when they reach the city.
