yo may be able to, but the CF is so much faster than any hard drive will be that that the device may fail even if you do rig it up, as, due to the extremely high latency, it may think that it has a CF that has just been completely shot.
then of course is the physical size difference...
however, for a price i may be encouraged to work on a design ;-) that would probably defeat the purpose of saving money though ;-)
