The axles of light MTB hubs are all different, but basically all of them would need custom axles and spacers to convert from 9x100 QR to 10x120 bolt on. The only hub I know of with a drop-in conversion is the heavy Shimano XT because it has cup and cone bearings which, unusually for a front hub, are 10mm threaded. Of course, any cartridge bearing hub with bearings of 12mm or greater ID can easily be converted to take a standard 10mm steel track axle and track nuts, but that ends up just as heavy as a light track hub.
