Could you look at a broader spectrum maybe? I had to do something similar (find a unique title) for a classic civ paper. Most of them seemed like they were focussing really tightly on one thing. Parthenon friezes, Hellenistic art, pots by Exekias, yadda yadda. I ended up doing "development of the horse in greek art 40BC to the Hellenistic period," which was accepted as even though it was pretty broad across the history I focused on one thing, i.e. horses.

A development question might help you find a topic that is similar to something already done, but rather than simply saying what happened when (as they might have), you'd need to do some actual analysis of how it changed and what importance those changes had.

Not sure if that helps, but it something to think about?
