[boxstershorts]

To do the mod you would have to rotate the gauge face and probably cut off the part that would then cover the digital readouts. Then you would put the needle back on in the correct position (not that straight forward...and you want to get the needle position right!)
It would probably look like really poor workmanship at the very least. You would also have to cover the exposed LEDs that normally light up the top part of the gauge face.
Unless you can find a place that can make a custom gauge face...probably overly-expensive.

And everytime you pull a needle off your cluster, you risk breaking the fragile motor inside. (Don't ask my why I know this...grrrr! and I was REALLY REALLY careful).

So it's probably a mod that you would reserve for track boxsters
