Aye, swoops would be awesome as personal mounts, but I think they would be a little impractical seeing as how inhumanly fast they are. It could be interesting, if they work that out. As far as transportation goes, we only have local animals, speeders, starfighters and swoops in Star Wars, so the chances are good.
I'd personally love to see some sort of a swoop racing championship in the game, complete with charts and stuff. With the MMO thing, we may even have off-track fighting, backstabbing, espionage, sabotage, team-ups and god knows what other possibilities.
