Altough wearing similar customes, there were no 2 speedies, Thea is Speedy & Roy was Arsenal. Laurel is the Black Canary, same for Dinah Drake (her successor, like in the comics), Sara was the Canary and now the White Canary. Evelyn was just a copy-cat so can't really compare her to Black Canary, she was going to take up the mantle of Artemis before stuff happened. Also, if Ollie had come back as the Arrow in S4 instead of GA, they would have restarted the manhunt for the Arrow and he couldn't inspire the hope on people, which he longed for.
