The developers have already gotten a movie-accurate Death Star map planned out, they say. No need to call upon the horrifying might of Titan mode
.
As I've said before, I think a better candidate for Titan mode would be something like two cruisers such as Corvettes, flying low over a planetoid. Larger ships such as ISDs need whole maps to do boarding of them justice (cough, ISD Judicator map for GC, cough).
