I would actually consider a Resistance A-wing fairly likely. I realize that the A-wings in TLJ were RZ-2s, but it is in canon that the Resistance also used some RZ-1s as well, especially earlier on. For that matter, I wouldn't be too surprised if they get a Z-95 (Poe flew one) or even a T-65.
Though I doubt the same would go for the First Order re: bombers, interceptors, etc.
