What If Nightwing lead the Arrowverse?

After the success of the Dark Knight trilogy, the CW conceived Arrow to piggyback off that success. However, Green Arrow and Batman are two different characters, which meant sacrificing a lot of what makes Green Arrow great. Because of this along with what the universe ended up turning into, I believe that Nightwing should've been the one to start the CWverse instead of Green Arrow. I may elaborate further in another post, but here is what I think the CWverse should've looked like.
