Hi Michel, I did not know about that module but it looks very interesting. How old is the module? I didn't spot the switching frequency mentioned in the PDF specs. It must be quite low for people to be able to actually hear various resonations in the audible range?
But using discrete components in a boost topology with a modern switcher and off-the-shelf inductor you should be able to get at least a 200kHz supply going. If not 1MHz. Not sure about the noise but if you're not loading it heavily and you have a good efficiency design, surely it could be minimal? If I were building the kit I might actually want to wind my own inductor. You could furnish the core and wire as part of the kit? You could also have the commercial HVPS module mounted on a plug-in daughter board, that way you could just redesign the daughter board around any module in the future and customers could replace it. Finally you could also investigate a switched-capacitor power supply, I've not played with them yet. Wonder if there is a chip that can stand off enough voltage to at least drive a voltage doubler array to get the voltage you need?
