But I'd let them keep their names. Just because the names are pop culture references doesn't mean you have to run a "Star Wars" based Eberron campaign.
However, if they are actually EXPECTING you to run the campaign with constant Star Wars themes running throughout, I'd disabuse them of this notion quickly.
So the short answeris: Ignore the names and run your campaign as you see fit.
