As star said ,the appearance would have a massive impact on kaldur (if she's actually dead which i believe she is).

Why do you think the Blackest Night was so effective? they had heroes and loved ones restored from deaths which greatly affected the heroes and had them go after their loved ones. Some of the heroes werent even willing to fight their loved ones so it was basically just rolling over and letting the uber zombies take everything over. Since Kaldur is not over Tula, it'd have a similar effect on him even if he knew it was Miss Martian.
