Obviously that would never happen, but it is more about trying to build Power Girl's character back up and giving her deeper ties to established DC characters. The only way Power Girl has been appearing at all in DC books the last few years is because of her friendship with Harley Quinn. So those ties and connections are important.
Talking about her rogues or supporting cast feels a bit much when she can't even appear consistently in an ongoing DC series. So a romance with a Nightwing could be a way to increase her influence, and also lot of fun if done properly. As both characters have similar upbeat and outgoing personalities, are two of the most attractive heroes in the DCU, and fall into similar roles within their hero families with growing up and creating a new hero identity for themselves. So they have a lot of similar experiences writers could use. A romance with Val again isn't going to do anything for the character with where she is currently. You build her up more and then use characters like Val.
Dick hasn't dated Starfire in 25 years and hasn't dated Barbara in like 13 years, but with them all having so much baggage you can't really have them start a new romance from the ground up with each other. So Power Girl would be something fresh. It would eventually end but it could transition into a good friendship between the two, and gives Power Girl a direct connection to a Batman family character with Helena Wayne not being around consistently. Dick is the only main Batman family member without his own Superman family connection. So it fits. Maybe the dynamic could change to a Batman and Zatanna kind of dynamic where it is a close friendship with underlines of romantic tension that people enjoy, but no one expects it to replace his relationship with Catwoman.
