Actually, you can probably increase the OLD, but it has to be by the same amount on each side.
Although IIRC these have cartridge bearings and proprietary axles, which doesn't make it easy.
In fact, if you have a steel frame with horizontal dropouts, you can just pull the right dropout further from the centreline... obviously quite a kludge, but it does make for less dish for a given number of cogs at the expense of either chainline or a wider Q factor, not to mention symmetry and cross-compatibility. I guess the wheel would be vertically angled very slightly to the left, too... not so great. Although you could make it good with a file, which would also let this work on a bike with vertical dropouts.
