Sadly, Mass Effect doesn't lend itself too well to fighters. Most ships are simply too big to be bothered by fighters unless they use disruptor torpedoes, which are even slower and easier to shoot down than bombs in FS. Ships also have excellent point defense systems with their light-speed GARDIAN lasers, so fighters just Zerg rush and spam said disruptor torpedoes in the hopes at least one gets through. Its stated that while a shot from a GARDIAN laser can't destroy a fighter in a single shot, it can damage it, forcing it to return to its mothership for repairs. So a ME mod for FSO would have you be an anonymous fighter pilot who basically launches massive, slow bombs at enemy cruisers and dreadnoughts. I've read the codex and I don't think it mentions fighters ever used for intercept duties, probably because at the speeds ME combat takes place at a human pilot would be unable to effectively target something as small as a fighter. On the other hand a game like Sins of a Solar Empire would be great for a ME mod, if you could assemble the needed assets.
