I don't believe unparadise. Has anyone actually seen its definition in mw? Because if you put in a similar word, e g unparadis, it doesn't come up. I have an idea they put anything that is a word with un- in front of it there!
There are at least two words that can follow HAGI.

The 1913 Webster's Revised Unabridged Dictionary -- which is available online at
1913 Webster's Revised Unabridged Dictionary
-- defines "unparadise" (which I have admittedly never heard anyone use in a sentence) as "To deprive of happiness like that of paradise; to render unhappy."

(Hopefully, this word won't have the early-death touch of the last two.)
