Will the 85 mm crampon work on a ski with an 88 mm waist? Maybe with a little bending? Next largest size I've seen is 105 mm, not currently for sale.
Maybe, but usually not with great results. The ski edges might get a little torn up and the crampon will go in at a slight angle, making it less effective. I would measure the area of the ski its going to contact though...sometimes the specs aren't exact and you might be able to make it work.
The crampon body is pretty stiff. You are much better off getting the 105mm. They should be available in a few weeks.
