Fan Casting The Riddler/Edward Nygma in Batman 5: Knightfall

Would don his Riddler attire, and I would make it slightly armoured, especially his hat, is kind of pretending to be a hero but not? His tech and equipment would be supplied by Elliot. Would still have Caldwell security guards as well as his private vigilante taskforce. Would capture various officials who disagreed with him and place them in Riddler traps? Saw style?
