I'd cold space it - it's a piece of piss as long as you take it easy and check alignment. Respacing cartridge bearing hubs is quite difficult because you need a special axle with a thicker central section to fit the hub, rather than just a uniform width threaded axle. Given that Miche hubs use Italian threading you'd be very lucky to find one and your best bet would be to get one custom machined.
Sorry for the thread necromancy, but I'm wondering about this point because I've got an old MTB with a cartridge-bearing rear axle I'd like to respace for a BMX sprocket. Are all cartridge-bearing hubs impossible to respace without replacing the axle? I've searched around with google and there are very few references to it. Even Sheldon's silent on it, so I thought I'd post on here.
