In my post a few posts back I listed off all those characters that have had solo series since the 90s and none of them in that time have developed a notable rogues gallery. Just like Nightwing. So I don't think it is possible to create a rogues gallery the way people want in modern comics.
All top tier villains were either grandfathered in from an era where comics had a lot more influence and were more widespread. That includes a Deathstroke who was created in the 80s back when NTT was selling as much as any comics and competing with the X-Men, or new top tier villains now are funneled through a very few "main" comics that have been around since the Golden/Silver/Bronze ages like a Batman, Superman, Justice League, Spider-man, and so on. No other solo books outside those top ones have really produced any real top tier villains. So expecting a random Nightwing villain to suddenly jump up into being this super notable villain doesn't seem feasible when there aren't any examples of it happening.
Deadpool is the biggest solo character that has gotten their own solo series since the 90s, basically since Nightwing got his own solo book, and despite Deadpool's books being very successful none of those books have created any villains you'd put on the same level as the top ones from the Big 2. So I'd just focus on trying to take big swings with already established big villains regardless of the franchise they are from until you get a story with one of them that is a success. Since if the story is good no one will care where the villain is from. Sure, you can still use new original villains here and there but then you can't complain about Nightwing's rogues gallery at the same time.
