Then surely it's a cheaper and quicker option to just buy a new freewheel? Unless you're calculating that the hope hub will out last it's values worth in freewheels, which makes more sense to do.
To be honest if you get a new hope hub then mill it you'll loose you're warranty, unless you already have a second hand one (or third/fourth/fifth so in), then you have to give it to someone who might not do a proper job and takes forever. Potential f**k up plus time waiting for it, I'd just get a new freewheel lol.
