The most appropriate example for your opinion would be Fafnir. Yu Long is an Asian dragon and those look like snakes with legs, Ophis does not have a specific appearance she can just change her appearance to her liking. Issei's body was rebuild with the flesh of Great Red a Western dragon and the only example of one of them not having wings is Fafnir.

And I think he'll get his own wings is because of Great Red's flesh and I hope he will be able to look like a humanoid dragon when using a mastered dragonification and I think that form would need its own wings (appearancewise I think he would resamble a small Grendel in regards to body frame).
