You cannot own two items named Kikoku, regardless of stat or level difference.
Has this actually been tested with a relic, mythic or empyrean? I wouldn't count something like Ursine Claws +2 because the base weapon is exactly the same, whereas the difference lies in yellow augments. Level 75, 80, 85 and 90 relics all have different item IDs.

If it's been tested, I feel pretty lousy for the person who tried it.
