Yes the idea for this will be v. short haul for now which is why they talk about London to Paris; ~215 miles. 25 times further (50x lower energy density, 2x better engine efficiency) would be under 5,400 miles.

Looking at the empty weight, the weight of max fuel capacity and range[1], it seems realistic to fly 200-300mi on batteries without any kind of jettisoning.

So it seems feasible, the next question is where could it be in terms of commercial viability.
