Justice League, Injustice Gang match-up

[Batman 80]

Superman-Luthor
Batman-Joker,Copperhead(I read somewhere that he was a Batman villain)
Diana-Cheetah
Flash-Shade
Green Lantern-Star Sapphire
So who do Grundy and Ultra Humanite match up with? Does Grundy match up with J'onn and Ultra Humanite with Hawkgirl?

I would imagine it's Hawkgirl vs. Humanite, since they fought in JSA in the comics.
