If you have a selection of these filament transformers, pick one that has the lowest amount of stray capacitance to the primary and/or the metal lams. To reduce the high frequency loading that that stray capacitance may do the higher frequencies of the video signal on the picture tube cathode you could use a pair of say 10uH coils in each heater wire between the new transformer and the picture tube heater. Those Sony isolation transformers may have enough inductance to do this. Its primary coil would be one of the inductors, and its secondary the other inductor. Phasing will make a difference though. Be ready to swap the ends of its primary if the video looks low passed.
