Would be cool if we could find a good way to do it though!

It seems like the core of this problem is that we're unable to express the problem succinctly using our existing language/toolset (NUnit). It's not complex for a human to define the proper mapping (say by drawings some arrows between two boxes on a sheet of paper), but it is complex (or just seems that way) to do so in NUnit.
