Sure, he doesn't _need_ to write any gay characters or material into Star Wars. But I'd bet you dollars to donuts that he'd be forbidden to do so, and that even if he got this gig, they'd put a lot of restrictions on what he was allowed to write about. And that's unlikely to result in anything good. Action/adventure isn't Smith's strong point. He's proven he can do it, as in Green Arrow, but his best work is marked by character stuff and a willingness to explore taboo topics like sexuality and religion. He wouldn't be allowed to do that in Star Wars.
