I would like to suggest you for focusing on research gap in your own area - what is really required and how important your findings that can positively impact our. Finding a research gap and having the means to develop a complete and sustained study leads to novelty.
I agree with Denis.... there are topics that are very important and need many variatations on a theme in order to truly understand the nuances involved.... If you feel you have something new to add to the discussioin/exploration by all means conduct your lens on this topic....
