You could do what I would like to do, but don't have the time.
Do a molded carbon fiber cluster with Autometer gauges. There is a company that makes one that is sort of cool, but they want way too much for it. If have ever done fiberglass work, then it's the same concept, only use carbon mesh with fiberglass resin.
<edit> Like this, only cooler. I would use the stock locations and have a little better shape to it.
