I've been in a (little) CB in a PA28 and I can absolutely assure you, that whatever the numbers may say, you do not want to do it.
I believe that we were lucky to get out in one piece, as the VSI pegged one end of the scale and then the other and the airspeed fluctuated between 40 (bottom stop) and 120 knots.
Fortunately we did not encounter ice, otherwise I reckon that would have been that.
