I would highly recommend you don't use those tiny transformers for several reasons:
1. They are tiny; physically and power wise. If you start pumping a couple hundred of watts through those poor things, they will most likely go up in flames before you know it.
2. The primary probably isn't center-tapped. A ZVS driver requires a winding that is center-tapped.
3. It would be very impracticable to gave to fiddle with the tiny wires on that thing.
I don't see why would would need to use those things anyway, they are only designed to run small backlights and probably only put out 2-3 kV at less than 1 mA. Just stick with the flyback, a lot more voltage and current possibilities.
