I think Bossk is right, most people won't make the connection, and so as long as you don't go overboard, you should be able to keep the actual spellings, which means that Jacen and Jaina and even Bastila could be perfectly fine names for children. Keep in mind that there are a growing number of bizarre names springing up these years (and a lot of them are androgynous, to make matters worse). We live in an age that's moved beyond John and Mary. I've even heard of kids name Montana and Dakota, and I'd give a child a Star Wars name far, far before I'd name a child one of those names.
