The problem with modifying a power supply from 200V to 300V is that quite a few components will probably go out of spec. e.g. the output capacitor and the feedback resistors. Bringing them back in to spec may involve changing the footprint and so is not a simple mod to make to a board.
If you can get a single inductor module, you may be able to use a voltage doubler on the pre-rectified output to get the voltage you want, if not the current.
