I think that yeah, this should only work with certain enchants/curses, and on weapons only (until we get more body enchants). Those being-
Rebelling
Divine
Floating
Blessed
Reaper's
King's
Fated
Parasitic
Demonic

In addition, to do a dual enchant, I think it should add 1 difficulty to the higher of the two enchantment difficulties.
