I wouldn't, because:
1. By the time you find and buy a 2" barrel, extractor rod, and center pin; and pay a gunsmith to properly install them, you will have spent nearly enough for a second gun. Maybe leave out the "nearly".
2. A 2" K frame is still not a small gun and is not an optimum "snubby." I have a Model 12 that does not get out often becaus of its bulk, even though it is light in weight.
