Maybe you could ask the public/TSR for their opinions on whether it should be reintroduced and, if so, under what conditions (i.e. for what offences?)
I did my EPQ on economics so I obviously did it in a completely different area to you, however my supervisor said that if you put primary research into your EPQ then it can get you some good marks (a friend did his EPQ on corruption in Indian schools and interviewed a student and a teacher over there for primary evidence).
