There's chatter that Damian Wayne is going to die in Batman, Incorporated #8.
While I don't want to see that happen -- Damian has really grown on me over the years, though I think he worked better with Dick than with Bruce -- I realize that Morrison has been building up to this for a long, long time. (Damian was supposed to die much earlier in Morrison's run, for what it's worth.)
If Damian does die, I'd hope we get an appearance by Stephanie.
First, she can relate to Bruce's feelings at losing a Robin -- since she was a Robin that he lost. (And if Damian dies, that means that Bruce lost three out of five to death. Never mind the fact that two of them "got better.")
Second, she treated Damian like her little brother and tried very hard to socialize him to the point where, outside of Bruce and Dick, she was the Batfamily member he had the most respect for.
Do I expect Stephanie to appear in a comic after Damian's (hypothetical) death? No. But it makes so much sense that she should that I feel like DC would be missing an opportunity.
