I was really surprised that nobody had posted a thing about Felicty due to her increasing popularity in Arrow. So I must say that I totally agree with you, she has become so popular that she has earned the right to make it into the New 52, just like Harley Queen, Chloe Sullivan or even Mercy Graves (whose impact in the media was insignificant). I'm absolutely thrilled with the idea of the New Oracle, she'd be terrific!
I hope they use the classic iconic outfit she wears in the comic books instead of that bulky gladiator armour. She's a superpowered demigoddess, she doesn't need all that protection, on the contrary the armour would look more impractical in battle if she needs to fight or move freely
By the way, when supergirl was realeased everyone complained about how she arrived, speaking fluent English and having civilian clothes. Thor did the same everybody praised the film.... mmm... male chauvinism XD
