I built an ecclectic style that includes Northern Shaolin. It's just as effective as any other style out there. As long as you have a good knowlege of a system, you can apply JKD principals to it. Chances are it will work as well as you work it.
This is the standard modern JKD mix:
Muay Thai/boxing (maybe a bit of WC)
Mine came out like this:
Wu Ji/Shaolin (plus a nice hodgepodge of various Japanese techniques)
Shuai Chiao/Chin Na
It works just as well if not better. I might even dare to say it looks a bit prettier, lol. Just make sure to approach your training realistically. Do lots of sparring and forge your style into an effective art through "field testing." Cover all ranges of combat and then some. You will realize that it's not the art, but the artist.
