First thought IMO, is to book Gonzaga as the fill-in for Mir against Cormier, but talk about one helluva hard fight for Cormier's last SF bout. Gonzaga's a damn sleeper and hasn't been on the big stage in a long time, so it isn't like he's a draw like Mir, while I'd hazard he's as dangerous, if not moreso than Mir.
I still think Kongo is the safest choice. Finish off Cormier in SF and give him a massive debut in the UFC.
