Stick with a spur drive -- there is a down side to using a chuck and the tail stock at the same time. If your machine is not perfectly aligned, you will know it since either the tail center will draw a circle on your blank or will move the blank in the chuck. Zillions of spindles have been turned between centers so it DOES work. Chucks and face plates are for bowls, boxes, hollow forms...
Note that if your headstock and tailstock are not perfectly aligned, there may be a little motion at the headstock end when turning on a spur drive but usually it is of little consequence and you probably would not even notice it. It does not introduce error into your work.
