Considering that the operating costs for electric is forecast to be about 30% (and possibly as low as 10%) of conventional propulsion, the economics will be there. We still have airlines like Cape Air flying Cessna 402s which only seat as many as 10 in some configurations and I don’t see anyone questioning those economics, so why not a 19 seater that not only costs less to “fuel” up, but also has considerably lower maintenance costs?
