Most HG freehubs will allow a 1mm spacer in addition to the cassette. If you just add thickness between the middle cogs and not the first and last, that will put you at about 1mm extra with all the cogs. At least with 8 speed.
(You don't need the extra space on the first and last because the stop take care of things.)
