It has a pretty sound, but I agree with @tori101 that if it were to be used you would need to accept and come to terms with the religious and political associations, some good and some not
However Im not a big fan of Salem either for the same reasons, and Rue can at times have a negative associations, so I think all of it combined comes off really heavy for me. And my personal style tend to be more positive and light, so I may be slightly biased.
But at the same time I really love the sound and positive associations with Jerusalem, so I guess it would all come down to what you associate with the most.
