I made a new curtain wall type called "Louvers" which has the fin as the interior mullions and a simple frame for the perimeter and nothing for the panels. I used has type-driven dimensions to keep the spacing of the fins. Once this type is embedded in a larger curtain wall, it automatically gets the spacing, adding and removing mullions (fins) as required. Worked pretty well for us.
