It would be possible, but as anyone who's changed their gauges will tell you, you have to be careful to get the needles in exactly the right place again. It's not impossible though!
If you have an OBD-II cable, you should find it much easier since you can drive with the OBD-II connected, and have someone read the speed off the laptop while placing the needle exactly in place.
PS Anyone want to sell me their old SVT red needles
