I am not saying you could not do that. But if the goal is to find the right UV blocking density of the Cone digital negative inkset, be aware that Cone provides profiles that will print to a rather wide range of effective UV blocking density. In practice you should be able to choose one that will print with the right blocking density for your process, then go directly to creating an .acv curve.
Testing for density range should be quite easy. First, find the correct printing time for Dmin with your OHP, then print out several step wedges with different profiles. Makes prints from the negatives and evaluate the prints. The correct profile for your process would be the one that has full shadow density at 95% or 100%, and some slight differentiation between 0% and 5%, with 0% almost or fully paper white.
