I would not do it...too slippery, 'cold' in Winter, too liable to have dropped things bounce away far too well.
Sheet Zinc is a wonderful old time Bench Top material, and well Oiled Masonite ( Watco or other drying Oils ) or smooth Oiled Soft Wood, such as Pine...would seem ideal to me.
Stainless is great for Food Prep or Mechanic things, since one can wipe it down easily for cleaning.
Even 'Dry Wall' ( easily flipped over or replaced if getting shabby,) or Green-Board, Paper Edge toward operative, ( over an underlaying Bench Top strata of course ) makes a very good surface for a Light Projects Bench Top...the Paper covering is friendly, never cold in Winter, things do not slide on it, wipes off easily with a dry cloth for clean up...can be easily edged-trimmed in Wood or painted even.
Real, old time light solid color 'Oil Cloth' also was pretty well an ideal for Light Duty project Bench Tops....and Oil Base Painted fine weave Muslin or fine Canvas, is about the same thing when done one's self.
