I did some tinkering and found a way to get what I want. I built lines connecting the center points of the circles in my top and bottom arrays and used those lines as axes of revolution and used points built from the end points of my circles to generate the profile curve. I'll post a shot of how it turned out. Point of interest: if you use the evaluate curve to get the points that build the profile curve you can get the frustums to taper in.
