Dogfighting was one of the worst, the rules for it made no sense, and I had revised them.They're the best ones I've found but very easy to break.
Basically you want a huge sized starfighter ideally something like an A-wing or one of the advanced TIE models and initiate dog fighters in it with the relevant feats and talents (heavy weapon specialist, skill focus pilot, hyperspace explorer).
A revised version of those rules would be a good player to start though. 5E kinda tones it down even if you ported them as written to 5E. +15 or more piloting checks lvl 1 isn't gonna happen.
I would LOVE Saga 5e-fied, but it's a lot of work to make that happen.
