Since the show started, they are introducing non-super-powered versions of some characters (such as Laurel and Count Vertigo). Would audiences be willing to accept non-super-powered versions of Clark Kent, Diana, Hal Jordan, et al.?
What would be the point? Those characters don't work without their powers and the producers have pretty much said there are no powers in this world.
I think the closest we'll get to powers in this series are hi-tech gadgets that simulate powers. Like some kind of sonic emitter for Laurel to wear around her throat.
