Direto or Drivo with shorter freehub/cassette body possible?

[Element2k3]

Seen that the shop where I ordered my Rampa from seems to be out of stock, I was wondering if it would be possible to fit a shorter freehub/cassette body so to make it compatible with a track bike with 120mm. I found online some 6 speed hubs for 120mm and thought to take the body off and install it on a direct drive.
I really can't understand why there is no option to use a track bike with a direct drive. Lemond for example had an adatper for it.
