If your hub is the same as the ones I have worked on, the real axle is a thin wall 1/2" diameter tube, Cr-Mo steel. The aluminum parts you see, that interface with the frame dropouts, are caps which are pressed onto this steel axle. You just need a longer cap. They are an interference fit but I don't think the force needed to pull them off is exceptional. I think I held the cap in a collet on a Bridgeport mill and held the hub body in a vise and used the mill's knee action to pull it off - probably overkill but if you have a Bridgeport just sitting there, it's quick and easy.

If I recall correctly, the overlap between the cap and steel tube is enough that you can add a 6 mm spacer without needing to remanufacture the whole cap. Don't count on my feeble memory on that, and yours may be different.
