Connect end of multiple swept rectangular profile

Hello, 

I have seen a few discussions that talk about how to sweep a rectangular profile on multiple curves.  Those are very helpful and I find them working for what I need almost.  I have created the brep but now I would like to know if there is a way to have the ends of the curves connect to one another smoothly.  I have attached a few screenshots of the model I am working with. Basically, I am trying to have an end result where the frame or silhouette of a complex geometry is piped with one continuous brep that is created from a rectangular profile that has been swept along those curves.
