The potential problem I see is too much upper bass energy (100 Hz ballpark), unless you use a very large cabinet either sealed or tuned deep. Assuming the published T/S parameters are correct, a single F200A will normally be putting out adequate upper bass energy, and two of them in a bipolar format will be adding in-phase in that region so you could get an overly warm or even thick-sounding presentation, especially with a high-output-impedance tube amp.
